Early-blooming perennials for shade or morning sun

May 31, 2023 • Leave a Comment

by Richard Tuttle

When my wife and I decided to plant the ground under a few of our trees and shrubs, some friends suggested various fast-growing groundcovers like vinca or English ivy for these darker spots, but we knew how invasive they could be to surrounding beds or natural areas. Also, we were avid, if inexperienced perennial gardeners, and wanted to try out everything under the sun (or in this case, under the shade), but had limited areas beneath the few shade trees and large shrubs on our property. With a little research we soon learned that some of the trees that provided shade for us, namely silver and Norway maple, also had such dense and shallow root systems that growing anything under them, even lawn, would be a challenge.

In the remaining shady areas, we prepared our future shade beds by first spreading 6 to 8 inches of municipal compost (made by the city from leaves and ground-up brush) and then gently rototilled it to mix the compost with the existing soil and all its micro flora and fauna. Then we dug pathways so that the planting and future weeding and mulching could be done without walking on the beds. Once planting was complete, we mulched with a few inches of leaves (don’t use unshredded oak leaves—they can smother plantings). The following plants are standouts that have prospered through the years.

Bloodroot (Sanguinaria canadensis)

Despite an all-too-brief week or two of blooms, bloodroot is well worth planting. During a warm spell in late April, it appears out of nowhere. The cupped, scalloped leaves with their red sap are quickly followed by white-petaled flowers with gold stamens (centers). Our favorite variety (‘Flore Pleno’) has doubled flowers and fewer stamens. The double form seems much more vigorous and stays in growth much longer than the single form. Unfortunately, the doubled bloodroot seems more prone to rotting and must be divided regularly to avoid this. Grow bloodroot in deciduous shade.

Lenten rose (Helleborus orientalis)

The popularity of hellebores rivals hostas for the premier carefree perennial for shade to part sun. Plus, they are resistant to deer. They are one of the first perennials to bloom in our gardens and can continue blooming for months. The large showy flowers come in many different shades of red, pink, purple and white. They are truly perennial, lasting for decades and are tough as nails through periods of heat, humidity and drought. Their tough, glossy leaves also last all summer and well into the winter.

Wild ginger (Asarum)

Sturdy, easy and handsome groundcovers for shade, asarums acquired the wild ginger name because of the ginger-like smell that the roots give off when cut. They love organically-rich, moisture-retentive soil that is a bit acidic and has good drainage. Hardy to zone 3, our native species (Asarum canadense) is easy and spreads quickly without being invasive. European wild ginger (Asarum europaeum) is more showy with thick, glossy, dark green and leathery leaves, and is hardy to zone 4. It is a favorite, making a big shiny patch over the years. Everyone wants to also try the very handsome Asarum shuttleworthii ‘Callaway’ from Callaway Gardens in Georgia. It’s slow and expensive, but has striking patterns on the leaves. Some books say it’s hardy to zone 5 and some say zone 6. All I know so far is that it’s beautiful and growable in southeastern Michigan.

Lungwort (Pulmonaria)

Lungworts are old-fashioned perennials that are grown both for their early spring blooms of pink and blue and for their silver leaves that brighten shade gardens all summer. They make a good groundcover for shade because they form large clumps, but grow slowly enough to not be considered invasive or aggressive. They prefer some morning sun and if enough moisture is provided, even full sun. Like all woodland plants, a humus-rich, well-drained soil is best. Slugs and powdery mildew can be minor problems. The Chicago Botanic Garden did years of testing on over 30 varieties, considering disease resistance, hardiness, flowering period length and general adaptability. Among others, they recommended the following varieties: ‘Majeste,’ ‘Mrs. Moon,’ ‘Little Star,’ ‘Roy Davidson,’ and ‘Benediction.’

Variegated Solomon’s seal (Polygonatum odoratum ‘Variegatum’)

Several species of Solomon’s seal are native to Michigan woodlands and all add architectural interest to any shade garden with their graceful arching stems and fragrant pendulous flowers. Our favorite has creamy white variegation on the leaf margin and grows 30 inches tall and 12 inches wide. Over the years, clumps 3 to 6 feet wide can slowly form, so give it some space.

Barrenwort (Epimedium)

While not ranked as one of the showiest groundcovers, barrenworts have many virtues. For starters, deer avoid nibbling on them. Known as a low-growing groundcover for shade, they are tough enough to take even afternoon sun if they are grown in organically-rich, well-drained soil. They spread slowly so are not at all invasive and have attractive, mottled foliage and small but attractive, orchid-like blossoms in the spring (some people will shear last year’s tired foliage in early spring so that the flowers are more visible). Epimedium grandiflorum‘ Lilafee’ and ‘Rose Queen’ are classic favorites.

Marguerite daisy

May 16, 2023 • Leave a Comment

May is the season for annuals. Gardeners often seek annuals that provide maximum color and require the least amount of maintenance in full sun. One of the most valuable plants in this group is marguerite daisy (Argyranthemum).

Like many other plants, Argyranthemum was previously called a Chrysanthemum. Like most “mums,” they usually have daisy-like flowers that are available in shades of yellow, white, and pink. Flower size can range from only one inch across to almost three inches. Plant height can vary from only 8 inches to as tall as 24 inches in one season. They are not particular about their soil, but perform best in a well-drained, peat moss-based planting mix.

Marguerite daisies originated in Australia where much of the breeding is still done. There are many varieties from which to choose. The standard by which all marguerite daisies are measured is a variety called ‘Butterfly.’ It has dark green foliage and large, single, butter yellow flowers. It blooms from spring to fall and remains covered with a profusion of vibrant flowers up to three inches across. It is so hardy, it will even tolerate temperatures as low as the mid 20s. Removing its spent blooms is optional; it will continue to flower regardless. Landscapers love ‘Butterfly’ for its exceptional performance with minimal care.

Marguerite daisy Pure White Butterfly — **Pure White Butterfly** (Proven Winners)

In annual beds, ‘Butterfly’ is often grown behind the spiky, blue flowers of the annual mealycup sage (Salvia farinacea, such as ‘Victoria Blue’ or ‘Rhea’). This combination offers a classic contrast in color and texture. As an alternative to the mealycup sage, try blue-flowering summer snapdragon (Angelonia).

Marguerite daisy’s range of uses doesn’t end in the annual border. In the perennial garden, where flowers frequently come and go, annuals like marguerite daisy are extremely valuable. Because it resembles a hardy mum, most people enjoying your garden bed probably won’t recognize it as a perennial imposter.

Marguerite daisy Golden Butterfly — **Golden Butterfly** (Proven Winners)

‘Butterfly’ is also valuable in containers. One gardener I know created a very showy combination that fills the moss-lined, wrought iron window boxes on the front of her home. ‘Butterfly’ is the upright component that is intertwined with three spreading and cascading plants: blue fan flower (Scaevola), golden sweet potato vine, and pink petunia. The result is a showy splash of colors that you probably won’t find anywhere else in her neighborhood. To grow a planter like this at your home, just add water, sun, and some good potting soil.

Marguerite daisy Lollies Pink Pez — **Lollies Pink Pez** (Ball Horticultural Co.)

More “butterflies” have joined the original classic. Golden Butterfly is a golden yellow version. Pure White Butterfly has white petals with a yellow center. Breeders have been busy developing new varieties in a range of colors, including soft pink, medium pink, hot pink, and rose.

Few bedding plants have the versatility and performance of plants like ‘Butterfly.’ If you are looking for an outstanding annual for a sunny spot, give marguerite daisy a try.

Of all the perennial plants we have available for April flowers, rock cress (Aubrieta) is one that combines beautifully with early season bulbs.

Aubrieta has the common names rock cress and false rock cress. This is an excellent example of when common names can be confusing. Another popular rock garden plant, Arabis, is also called rock cress. Our focus here will remain on Aubrieta, whose characteristics are similar to Arabis.

Aubrieta ‘Dr. Mules’ — *Aubrieta* ‘Dr. Mules’ (Photo: Valleybrook Gardens)

Aubrieta is considered an excellent rock garden plant. Rock gardens can vary, but this term typically describes sunny gardens with smaller, shorter plants that look good growing among rocks. Alpine plants are usually rock garden plants; however, the term “alpines” refers to plants that originate from mountains, above the timberline. They are always compact to better withstand strong winds and are happiest in well-drained “rocky” soil. This is a little confusing, but it is interesting to note that most alpines are rock garden plants, but rock garden plants are not necessarily alpines. Aubrieta is in fact an alpine plant that originated on the mountains of southern Europe and Turkey.

Aubrieta ‘Whitewell Gem’ — *Aubrieta* ‘Whitewell Gem’ (Photo: Walters Gardens)

Aubrieta usually begins to bloom in mid to late April and continues into May. They bloom 4 to 6 weeks, which is twice as long as the popular creeping phlox. Plants rarely grow taller than six inches and may spread as far as 24 inches. Almost all aubrieta have mat-forming, gray-green leaves that hold their color and remain alive all four seasons. The only maintenance they may require is a light trim of the leaves after flowering is completed.

Their flowers are rarely over 3/4-inch wide, but are produced in masses. Flower colors include white, pink, red, blue, and violet. Many seed-grown varieties produce flowers in a range of colors. ‘Royal Blue,’ for example, has flowers of blue, lavender, and violet. ‘Royal Red’ has flowers in shades of red, purple, and magenta. For semi-double flowers, try ‘Bengal,’ which comes in shades of lavender, cerise, and purple. Some varieties are truly one color, such as the dark purple flowers of ‘Whitewell Gem’ and the fluorescent blue flowers of ‘Novalis Blue.’

Aubrieta ‘Red Carpet’ — *Aubrieta* ‘Red Carpet’ (Photo: Valleybrook Gardens)

Some aubrieta are grown from cuttings to more perfectly reproduce the desirable characteristics of the parent. ‘Aurea,’ also called golden aubrieta, has gold-yellow leaves that provide another attractive feature long after its blue-violet flowers have faded. ‘Aurea Variegata’ has bright gold and green bicolored leaves topped with blue-violet flowers. ‘Argenteovariegata’ forms a extra dense, 2- to 4-inch tall mound of creamy yellow variegated foliage and bluish flowers.

There are several other rock garden or wall plants for sun that bloom about the same time as aubrieta. Some of the more popular ones include Arabis, candytuft, perennial alyssum, pasque flower, and cushion spurge. All of these are great companions for bulbs that, like aubrieta, prefer well-drained, slightly alkaline soil and full sun. The blues, purples, and reds of aubrieta make perfect companions for pink tulips or golden daffodils.

Aubrieta ‘Argenteovariegata’ — *Aubrieta* ‘Argenteovariegata’ (Photo: Valleybrook Gardens)

The well-known garden designer Lauren Springer created a beautiful combination in her garden using aubrieta. She planted it with blue-leafed, donkey-tail spurge (Euphorbia myrsinites). Its chartreuse flowers are planted with the purple flowers of rock cress in a dry corner of her yard. She writes “it is perhaps the most psychologically effective combination in the garden, setting the mood for advancing spring, filling me with delight and anticipation each time I go in and out of the otherwise still dormant garden.”

After a Michigan winter, I think it is especially important to celebrate the long-awaited spring. If you can find or create a well-drained sunny site, try using aubrieta to herald the promise of another gardening season—just like Lauren Springer.

Joe Pye weed adds a stately presence to the fall garden

September 7, 2022 • Leave a Comment

**With its large pink flowerheads, Joe Pye weed brings bold color to the fall landscape. (Eric Hofley / Michigan Gardener)**

As the hot days of summer succumb to the cool, crisp season that is fall, many gardeners choose to take advantage of this great weather for outdoor projects. Of course mums and black-eyed Susans will dominate many landscapes each September, but the huge palette of late performers is sorely overlooked and certainly deserves closer examination. Although there are many fall-blooming plants available, most remain very underused. Far fewer gardeners visit garden centers in the fall, and those that do often just look at the mums, pansies, and spring-blooming bulbs.

Great varieties of asters, anemones, pink turtleheads, toad lilies, sedum, and ornamental grasses are loaded with colorful flowers or beautifully textured foliage. Joe Pye weed (Eupatorium maculatum, syn. Eutrochium maculatum) adds large, stately flowers, a robust growth habit, and durability to your fall plant choices.

Joe Pye weed is native to North America, but is more commonly used in the finest gardens of Europe. In more dry and less fertile conditions, plants may only grow to 4 or 5 feet, but moist, fertile soil will produce plants up to 8 feet tall. Its pinkish purple flowers are produced in clusters that form larger clusters reaching up to 18 inches across. Large green leaves are attached to rich burgundy stems, resulting in a striking contrast of colors on each stalk.

How to grow

Plants prefer full or partial sun, where the stems grow strong and rarely require staking. If extensive soil preparation isn’t your cup of tea, Joe Pye weed may be the plant for you. It thrives in the moist, heavy soil conditions that are typical in mostly clay Michigan gardens. It is long-lived and extremely durable. In fact, a specimen in our display garden was once mistaken for a weed and almost completely removed. It grew back the following year and was covered with the large flowers that butterflies and bees find irresistible. Joe Pye weed spreads slowly but may eventually overstep its boundaries. This can be controlled in spring by dividing the whole clump or simply removing outside sections of the plant’s crown.

Companion plants

Joe Pye weed’s massive size makes it perfect to use in the back of a border. Combine it with other large, late bloomers that have contrasting colors, flower forms, and foliage. Try the blue, pink, or purple flowers of asters, especially the taller varieties like ‘Alma Potschke,’ ‘Patricia Ballard,’ and ‘Sailor Boy.’ The huge flowers of hardy hibiscus are available in reds, pinks, or white. Some rudbeckia varieties can also provide equally large plants and brightly contrasting yellow or gold flowers. For a great foliage contrast, try the silver leaves and lavender-blue flowers of Russian sage (Perovskia atriplicifolia). Position the massive architectural foliage of plume poppy (Macleaya cordata) next to Joe Pye weed for a great combination of flowers and foliage. Don’t forget ornamental grasses—some of the larger types like switchgrass, feather reed grass, or maiden grass would provide contrasting foliage and winter interest.

In your front yard, where tidy and multi-seasonal plants are desired, Joe Pye weed may have a place. Its large size and controllable vigor work well in combination with common shrubs. Its flowers fill the need for a sizable fall-blooming plant where only rose of Sharon, summersweet (Clethra), butterfly bush, and blue mist shrub (Caryopteris) are common. Other tidy and multi-seasonal perennials for the front yard include upright sedum, daylilies, hostas, ornamental grasses, and of course, groundcovers.

Additional species

For a sturdier, more compact Joe Pye weed, the variety of choice is ‘Gateway,’ topping out at 5 to 6 feet in height. Plus, there are a few other species that are worth mentioning:

The coastal plain Joe Pye weed (Eutrochium dubium) has given us two slightly smaller introductions: ‘Little Joe’ and ‘Baby Joe’, both reaching 4-1/2 to 5 feet tall.

Hardy ageratum (Eupatorium coelestinum, syn. Conoclinium coelestinum) has blue, ageratum-like flowers on 2- to 3-foot tall plants that tend to spread.

Chocolate snakeroot (Eupatorium rugosum ‘Chocolate’, syn. Ageratina altissima ‘Chocolate’) has insignificant white flowers, but dark bronzy-purple leaves on 3- to 4-foot tall plants. ‘Chocolate’ will tolerate some shade. This foliage is incredible when contrasted with other gold, red, silver, or even green leaves.

‘Pink Frost’ (Eupatorium fortunei ‘Pink Frost’) boasts variegated leaves with white edges and pink flowers that pop when contrasted with the foliage.

These varieties, like Joe Pye weed, will tolerate moist, heavy soil, and prefer full or partial sun.

As fall approaches, remember that the gardening season is far from over. Gardening becomes even more enjoyable and plants tolerate being moved more easily when temperatures are cooler. Take a moment to evaluate your landscape and see where late season interest is needed. Perhaps try Joe Pye weed to add color, height, texture, and architectural interest to your fall garden.

Sea thrift

May 16, 2022 • Leave a Comment

by George Papadelis

Many good gardeners have fallen prey to the notion that all perennials are low maintenance, long-lived, and long-blooming. Many of these same gardeners became familiar with perennials by buying those plants that were more common and readily available. These often included forget-me-not, delphinium, columbine, hollyhock, and sweet William. These are all beautiful, easy-to-grow plants. However, they are either biennials or short-lived. For the new perennial gardener, this may be the kind of experience that makes perennials “too hard to grow” and can discourage them from ever trying perennials again.

Bloodstone sea thrift (Armeria maritima 'Bloodstone') — **‘Bloodstone’ sea thrift (*Armeria maritima* ‘Bloodstone’) / Photo: www.PerennialResource.com**

Many perennials are, in fact, long-lived as well as long-blooming and low maintenance. Sea thrift or sea pink (Armeria) is all of these and much more.

The genus Armeria includes many varieties that vary in height, flower color and size, and leaf shape. All of these have narrow grass-like foliage, and globe-shaped blossoms that range from rosy-red to pink to white. Heights can vary from 2 to 18 inches. The individual flowers last for three weeks beginning in May, but will continue to be produced through July into August if the spent blossoms are removed. One of the unique features of sea thrift is its ability to produce so many showy flowers from a relatively small clump of grassy foliage.

Sea thrift is native to many parts of the northern hemisphere, where the soil tends to be less fertile and well-drained. The rocky, sandy, unamended soil that sea thrift prefers can usually be attained in your garden by incorporating gritty sand and small gravel into the existing soil. Sea thrift also prefers dry soil and sun. With minimal water, soil preparation, and fertilization, it is a very durable, yet rewarding perennial.

One of my favorite species is the tiny Spanish thrift (Armeria juniperifolia). This one has a very tight tuft of needle-like foliage that only stands 1 to 2 inches tall. It is covered with 3/4-inch lavender pink flowers on short stems only one inch above the foliage. After 1 or 2 years, the mound may grow to become only 4 to 6 inches wide. This little gem is outstanding for small rock gardens, miniature gardens, or trough gardens (rustic-looking containers made from a concrete-like material and planted with small rock garden plants). Also look for this one in a white form called ‘Alba.’

The most common sea thrift is ‘Splendens’ (Armeria maritima ‘Splendens’). Its species name “maritima” is derived from its tolerance to salt, which enables it to grow along coastlines where few plants can survive. It reaches a larger height of 6 to 10 inches and grows about 10 inches wide. The dark pink flowers are 1 to 1-1/2 inches wide and rise well above the foliage for a more noticeable display from a distance. Use this variety in the front of the perennial border or in a rock wall for compact and showy splashes of color. The variety ‘Bees’ Ruby’ displays even darker pink flowers above 18-inch stems. A selection known as ‘Formosa hybrids’ has wider, longer leaves and produces flowers in a range of colors. All of these are easy to grow and have a long season of color.

'Splendens' sea thrift (Armeria maritima 'Splendens’ — **‘Splendens’ sea thrift (*Armeria maritima* ‘Splendens’) / Photo: David J. Stang/Wikimedia Commons**

Sea thrifts make great companions to other spring bloomers in full sun. Use their pink flowers in contrast with the blue flowers of other perennials like creeping phlox, dwarf crested iris, or ajuga. Take advantage of their early bloom season by incorporating spring-blooming bulbs such as yellow daffodils or blue grape hyacinths. Don’t forget to include some silver foliage with these pink and blue flowers. Try an artemisia or the non-blooming form of lamb’s ears (Stachys byzantina ‘Silver Carpet’). All of these make great, long-lasting additions to a showy spring perennial border or rock garden.

Armeria promises to provide years of color from plants that ask very little in return. So, if you’re ready to grow some plants that fulfill your original perception of the perennial gardening experience, try the low maintenance, long-lived, and long-blooming sea thrift.

Tarda tulip

March 21, 2022 • Leave a Comment

As spring bulbs begin to emerge, gardeners often wish they had planted more bulbs last fall. Few “perennials” are this easy to plant, grow, and maintain. However, many bulbs do have shortcomings. Some are planted and immediately become squirrel food. Others bloom so late that gardeners have to wait a few extra weeks for the foliage to die back before annuals can be planted. And the largest concern is their failure to bloom for more than a few years in the garden. Tarda tulip may help you overcome some of these potential problems.

Every year, in late April to early May, each tarda tulip (Tulipa tarda) bulb produces 4 to 6, star-shaped flowers that are about 2 to 3 inches across. The yellow buds open almost flat, revealing bright yellow petals whose lower half is white. Unlike most of the showier hybrids of today, tarda tulip’s flower size and color lends itself to a more refined and subdued display.

Tarda tulip is one of several tulips that can be found in nature, especially if you happen to be walking around the rocky slopes of rural China. Therefore, it is referred to as a species tulip—it hasn’t been bred for bigger blooms or brighter colors. Like several other species tulips, tarda tulip is extremely hardy. Severe winters and hot summers rarely threaten its vigor. This is especially true if you can create well-drained soil that is amended with organic matter such as compost or shredded pine bark. Plant bulbs at a depth of 6 inches in full or partial sun for best results.

The other great feature of this species tulip is its ability to flower year after year after year. Many of the more popular tulip types such as parrots, doubles, single lates, etc., have exceptional flower colors and forms. These, however, rarely last for more than a few years in the garden, even with the best conditions. On the other hand, tarda tulip is a true perennial type and should last for many years with minimal or no effort.

Tarda tulip’s short, yellow and white flowers make excellent partners for slightly taller tulips. Try a rock garden tulip (Tulipa greigii) for a 10- to 12-inch background. Then use the durable blossoms of grape hyacinths as a contrasting blue, spike-shaped flower that grows to about the same six-inch height. Don’t forget spring-blooming perennial groundcovers such as creeping phlox or candytuft. These can be planted right over tarda tulip for a brilliant, double dose of color every spring.

As for the squirrels, I can offer some ideas. The most reliable deterrent is to plant your bulbs under a piece of chicken wire that is buried below the soil surface. It always is effective but can be a chore to install and is especially annoying when it gets in the way of other plantings. Repellents can also be applied to bulbs before planting. These eventually wash away, but usually succeed because bulbs are the most vulnerable for a few days after planting. The good news is that tarda tulip is one of the least expensive tulips available. So, an occasional loss to Mr. Squirrel isn’t as economically devastating as it would be with other, more costly bulbs.

In the fall, tarda tulip can be found at many garden centers alongside other species tulips. Try these true perennials in your toughest areas and take advantage of their durability and beauty. It’s likely that these little gems will outlast your other bulbs and may even spread to fill nearby open spaces. Just remember to watch out for the squirrels.

Tarda tulip

Botanical name: Tulipa tarda (TOO-lip-uh TAR-duh)
Plant type: Bulb
Plant size: 6 inches tall
Hardiness: Zone 4
Flower color: White tips & yellow centers
Flower size: 2-3 inches across, star-shaped
Bloom period: Late April to early May
Leaf color: Green
Leaf size: 5 inches long

Butterfly weed and other milkweeds

July 7, 2021 • Leave a Comment

by George Papadelis

It turns out that one of Michigan’s most common roadside “weeds” is actually an outstanding perennial for our Michigan gardens. The brilliant orange flowers of butterfly weed (Asclepias tuberosa) can be seen blooming profusely in June and July in some of the most unfriendly sites one can imagine. Open meadows, steep slopes, and grassy fields can provide its only two cultural requirements: full sun and dry, well-drained soil.

Butterfly weed was given its common name for appropriate reasons. When in bloom, its flowers seem to attract butterflies from miles away. Monarchs are perhaps the best-known visitors to members of the milkweed family (to which butterfly weed belongs), but many other species dine on their nectar as well. Painted ladies, swallowtails, and others find it irresistible. All milkweeds are suitable lures for butterflies, so select the variety that best suits your tastes.

Butterfly weed, with its flat clusters of small orange flowers, is actually one of the few perennials available in orange. Its perennial companions in this narrow color range include poppies, red hot poker, daylilies, lilies, and crocosmia. Butterfly weed is also available in some different hues. The variety ‘Gay Butterflies’ offers a mixture that includes orange, yellow, and red. An all-yellow variety exists (‘Hello Yellow’), but is often difficult to find.

More milkweeds

Butterfly weed has another North American relative with the less flattering common name of swamp milkweed (Asclepias incarnata). The common name comes from the milky sap produced from broken stems or leaves. Swamp milkweed varieties offer flowers similar to butterfly weed, but in two different colors. One called ‘Cinderella’ produces larger, rosy-pink blossoms on more compact flower heads. ‘Ice Ballet’ yields all white flowers that create the perfect backdrop for brightly-colored butterfly visitors. Both will grow about 3 to 4 feet tall.

Tropical milkweeed (Asclepias curassavica) is another popular species of asclepias. This annual form can begin blooming as early as May when cultivated in greenhouse conditions. It produces extra vibrant orange and red bicolor blooms from spring until fall. Besides a sure death every fall, it offers everything available from the perennial forms, but boasts a longer bloom time. Like its longer-lived counterpart, this annual can also have a place in the perennial border.

How to grow butterfly weed

Butterfly weed is difficult to propagate. Seeds are tough to germinate and it also has a taproot that makes it almost impossible to divide. Even transplanting can be problematic. Garden centers are the most reliable source to obtain young starter plants. Once established in well-drained soil, butterfly weed can flourish for several years. Competition from grass and weeds is rarely a factor, but tree roots may pose a problem. Heavy, moist soil (which often occurs in southeastern Michigan’s clay) must be amended with coarse sand, compost, and/or pine bark to improve drainage. Otherwise, good garden soil is all that’s required for this two foot tall, native perennial to produce its flowers. In more harsh environments, evergreen boughs placed directly on the plants for winter protection would certainly be worthwhile. Be patient in the spring, since the leaves of butterfly weed, like several other perennials, are very late to emerge. Gardeners often mistake plants as dead and then discard them before new growth is able to develop.

Besides attracting butterflies and adding some color to your borders, all varieties make excellent cut flowers. Blooms allowed to remain on the plant give way to narrow seedpods, which provide an additional dimension to the plant. These can be harvested before they split open and dried as ornamental seedpods, adding a unique element to any flower arrangement.

Butterfly weed is a Michigan native that is both versatile and rewarding for the true Michigan gardener. Whether butterfly weed is in your yard, in a vase, or on the menu for a passing butterfly, it is one weed you’ll never want to pull out.

Gazania

by George Papadelis

Gazania are a multi-purpose plant with high-performance dose of both attractive flowers and showy foliage. They are one of the most durable annuals available for full sun, lots of heat, and minimal water. Gardeners in New Mexico and Arizona have made this one of their most popular bedding plants along with other heat tolerant annuals like vinca, verbena, and zinnias. Gazanias have brilliant 3- to 4-inch daisy-like flowers in shades of yellow, orange, brown, pink, red, and ruby. The individual petals are pointed, sometimes curled, and may be more than one color. The base of each petal may be uniquely marked by a completely different color such as olive, brown or black. Others, like the variety ‘Daybreak Red Stripe,’ have bright yellow flowers with a red stripe the full length of each petal. The flower centers of most gazanias are shades of gold. These bright color combinations and a history of low maintenance have made this African native popular.

The foliage of gazanias is also very attractive. The long, thick leaves of most varieties are blue-green on top and silver on the bottom. This silver sheen makes gazanias extra attractive even when they are not in flower. One variety called ‘Talent’ has flowers that are multi-colored and leaves that are very silvery on the top and bottom. In fact, they are so silver that plants that are not in flower are often mistaken for the completely silver annual called dusty miller. I love using this 10-inch tall variety as a silver ribbon to plant in front of blue annuals such as heliotrope or mealycup sage (Salvia farinacea). The gazania foliage and flower combo makes it perfect for containers when planted all by itself or with a cascading blue partner such as fan flower (Scaevola) or miniature trailing morning glory (Convolvulus sabatius).

Those of you searching for interesting annuals to help add color to perennial plantings may want to consider gazanias. The silver foliage of plants like gazanias can be used to combine and soften other colors in your perennial beds. Some varieties can be found with flowers of separate colors. The Daybreak series, for example, has flowers available in yellow, orange, pink, white, bronze, as well as the red-striped variety. The Chansonette series is available in six colors as well. These work well in both perennial plantings and annual combinations. Try a yellow variety with red salvia or an orange variety with purple petunias.

Gazanias have an interesting trait that should be considered before planting. If you would like to enjoy your gazania flowers in the evening, you may need to resort to a photograph. Gazania flowers close when the sun sets and reopen each morning. They also stay closed when it becomes cloudy and when it gets too cold. Therefore, if you need flowers 24 hours a day, gazanias may not be for you. On the positive side, gazanias are both frost and freeze tolerant. They can be planted in mid-April when few other annuals will survive. In fact, some parts of the country call this plant a perennial (it is hardy to zone 8).

Gazanias are extremely low maintenance. Once established, watering will rarely be necessary. Individual flowers last for several weeks so spent blooms will seldom need removal. Take advantage of this plant’s durability, versatility, and ease of care. Try it in your perennial beds, annual plantings, or containers. Even in your sunniest, hottest, driest area, its flowers and foliage promise to provide an interesting and showy display long into the fall.

Trillium

March 18, 2021 • Leave a Comment

by George Papadelis

For hundreds of years, trillium and its name have been used to symbolize purity, simplicity, elegance, and beauty. The name trillium has graced the marquees of restaurants, country clubs, resorts, software companies, consulting firms, and numerous other businesses. Every spring, thousands of Americans journey into the woods to admire the showiest of our spring woodland flowers.

In Ohio, where all 88 counties have masses of wild trillium, it was selected as the state’s official wildflower. Its flowers have twice graced a U.S. postage stamp. Even our Canadian friends across the bridge have declared white trillium (Trillium grandiflorum) the official provincial flower of Ontario. Other parts of the world share our passionate admiration for this plant. In Europe, where trilliums are not found in nature, gardeners dedicate vast amounts of time and money acquiring them, especially rare species. In Japan, a cult-like interest has developed. Gardeners have fervently established collections and written numerous publications describing them.

Trillium species

The most readily available species is white trillium (Trillium grandiflorum). This has large, pure white flowers up to five inches across. These develop in great abundance throughout the northeastern United States, including Michigan. Its flowers usually fade to a dull pink and sometimes red.

Red trillium (Trillium erectum) is a much more diverse species, with flowers ranging from red to purple to yellow-green and beige. It also grows wild in the Northeast and Michigan.

Yellow trillium (Trillium luteum) is the most common yellow species. It originates from areas around eastern Tennessee. One of its most notable features is the beautiful dark green leaves decorated with pale green markings. The flowers are relatively small.

Prairie trillium (Trillium recurvatum) bears maroon-purple to clear yellow flowers with strongly curved petals. Several other species and a few named varieties are readily available. Most varieties grow about 12 to 18 inches tall once established in the garden.

Companion plants

Trilliums typically bloom in late April or early May when dozens of perennials and bulbs are available as companions. Several spring-flowering bulbs will tolerate shade, and a few flower at the same time as trilliums. Try them with daffodils, tulips, Siberian squill, grape hyacinths, summer snowflakes, glory-of-the-snow, and Grecian windflower (Anemone blanda). Pansies and violas planted the previous fall or in early spring will offer the largest color range to coordinate with your trillium flowers. Early May-blooming perennials for shade include snowdrop anemone (Anemone sylvestris), foamflower (Tiarella), fern-leaf bleeding heart, leopard’s bane, and the beautiful blue-flowering perennial forget-me-not (Brunnera macrophylla). Several other woodland plants such as woodland phlox (Phlox stolonifera) and yellow dogtooth violets (Erythronium canadensis) should also be at peak bloom.

Growing trilliums

Trilliums are North American and Asian natives that typically thrive in moist, woodland settings where rich, acidic soil is prevalent. Gardeners with some shade can create this type of soil by incorporating organic soil amendments such as aged pine bark, Canadian peat moss, leaf mold, composted manure, or compost. During dry spells, plants may require some supplemental watering.

As gardeners, many of us have developed questions (or fears) about growing this somewhat mystical plant. It doesn’t help that the typical garden center only sells tiny, flowerless plants that show little promise of ever coming to fruition. Perhaps the most important aspect of appreciating this plant can be expressed in one word: patience. These small plants are much more durable than they appear. Most species will eventually develop into clumps of flowers that are quite persistent even in less than perfect conditions. This clumping process often takes 2 to 4 years. At least it’s faster than growing them from seed. If the seed germinates, it may take as long as ten years to bloom.

**Yellow trillium (***Trillium* *lute*um) / Photo: Steven Nikkila – Garden A to Z

Another perplexing aspect of growing them is the short period of time plants are visible in the garden. The “root” is really a sort of underground stem called a rhizome. This rhizome stores food all winter until temperatures rise in spring. In early May, the rhizome sends up branches that typically support three leaves and a single three-petal flower. The short time during which leaves are present is the plant’s only chance to gather energy from the sun. Therefore, picking flowers and leaves will diminish the plant’s ability to produce food. It won’t kill a healthy plant, but frequent picking will eventually reduce flowering. The number of flowering branches depends on the age of the plant, the size of the rhizome, and the overall energy stored in the rhizome.

Next comes the strange part. Just a few weeks after blooming, the branch and leaves wither away with no visible signs of life. The rejuvenated rhizome will await winter dormancy, which is mandatory for next year’s bloom production. Many woodland plants and spring-blooming bulbs (such as tulips, daffodils, crocus, etc.) enter an early-summer dormancy. These plants, like trilliums, are described as spring ephemerals. If you are thinking of shopping for a potted trillium in summer or fall, visually evaluating a plant’s vigor is almost impossible. However, a gentle probing of the soil to locate a firm, sleeping rhizome should do the trick.

Trilliums in the wild

Two species are currently on the U.S. threatened and endangered species list. Trillium persistens and Trillium reliquum only occur naturally in very small areas of the southeastern United States. In Michigan, one species, Trillium undulatum, is on the endangered list. This means it only exists in a few sites and is at great risk of becoming extinct in our state. Three varieties are on the Michigan threatened plant list: Trillium nivale, Trillium sessile, and Trillium recurvatum. Threatened plants only exist in a dozen or so sites and are at great risk of becoming endangered. All of the threatened and endangered trillium cannot be collected under any circumstances. All other trillium in the state of Michigan are protected in the following way. The only way these can be collected is by owning the land from which they are harvested, acquiring a permit to collect them from the Department of Natural Resources, or by acquiring a bill of sale from the property owner. All trillium located in national forests are also not collectible.

Since it is legal to collect unthreatened and unendangered trillium that are located on your own land, “nurseries” can own land from which they may legally collect wild trillium. Fortunately, responsible commercial collection of trillium has had little effect on most species. Almost all trillium have developed stable masses in their natural habitats, and more and more nurseries are offering wildflowers that are propagated on site. As gardeners and stewards of our environment, we should seek out these sources and avoid plants that are illegally collected.

The biggest two concerns for the sustenance of their populations are animal grazing and urban development. Repeated grazing from deer can eventually weaken plants and wipe out large areas. In regions where deer populations have increased, trilliums have often disappeared. A deer repellent would be a wise investment if deer browse in your trillium bed. In cases where a plant’s habitat is limited, populations are also suffering from commercial development. Clear cut lumbering and urban sprawl have an enormous impact on all wildflowers. In cases where development is unavoidable, the proper agencies should be contacted to save important plants. A great source of trillium is one that has a permit to rescue plants that would otherwise fall victim to bulldozers.

Trillium are available from many garden centers as spring-flowering plants in small containers. These can be treated just like any other perennial. More and more retailers are selling them packed in plastic bags with some peat moss. Make sure the rhizomes are firm and try to plant them before the leaves emerge. Bury rhizomes horizontally about 2 to 4 inches deep in the moist, rich soil that most woodland wildflowers love.

Remember to be patient—good things come to those who wait. In time, your little plant should form colonies that you and your garden’s admirers will enjoy for years to come.

Plant Focus: Crocus

September 1, 2020 • Leave a Comment

For a gardener, there are few sights as welcome as the first crocus of the year, peeking its flowers through the freshly melted snow of late winter. Crocus is a very hardy perennial and one of the few plants that can bloom as early as February or March. By being hidden deep in the soil, crocus corms are naturally insulated from severe temperature changes, ice and wind. Flowering is initiated by just a few consecutive days of temperatures above freezing. Once the first few inches of soil can thaw, flowers emerge and will last for several weeks despite more wintry weather. Crocus flowers can protect themselves by closing up in the evening and also whenever they experience severe weather.

**‘Yellow Mammoth’ (Photo: Dutch Gardens)**

Crocus have long been popular with gardeners for several reasons. Their durable flowers are available in many colors including yellow, white, purple, blue, and pink. One plant will usually return year after year and develop offspring that can produce additional flowers in beautiful drifts. The two-inch flowers are made up of 6 oval petals that surround 3 prominent yellow to orange stamens. Crocus grow from one-inch corms rather than actual “bulbs.” Both are just compressed stems: bulbs consisting of fleshy scales and corms being more solid. Gladiolus is another example of a corm.

**‘Whitewell Purple’ (Photo: John Scheepers, Inc.)**

Crocus are native to the rocky slopes of the Mediterranean countries and southwest Asia. They adapt to cold winters, full or partial sun, and well-drained soil. Most Michigan gardeners have the first two, but well-drained soil may have to be created if clay is prevalent. Drainage can be improved by adding aged pine bark or compost to your soil. Since crocus corms are planted 3 to 4 inches deep, only about 4 inches of soil below them needs to be well-cultivated. Corms should be at least 3 inches apart. However, this is the type of bulb that looks great planted in more natural and random masses.

Most crocus have only one serious threat to their perennial existence. Hungry bunnies seem especially tempted by the leaves, flowers and corms of several species. Corms can be protected by several methods. Gravel worked into the soil above the corms will make digging them up difficult. Liquid or powder deterrents can be used to treat corms before planting. Keep in mind that freshly planted bulbs and corms are most likely to create curiosity amongst browsers. Once established, they are rarely disturbed. If all else fails, you can plant in below-grade, wire mesh cages that are impenetrable. To protect leaves and flowers, apply a granular deterrent or a spray.

**‘Ruby Giant’ (Photo: John Scheepers, Inc.)**

There are many varieties of spring-blooming crocus but most of the hardy ones fall into four species. Crocus ancyrensis is golden bunch crocus. The selection ‘Golden Bunch’ produces up to five deep orange-yellow flowers in a “bunch” per corm. Of the four species, this is one of the earliest to bloom; late February is not unusual if Mother Nature is cooperating. This is also one of the more vulnerable to attack from the bunnies.

**‘Jeanne d’Arc’ (Photo: John Scheepers, Inc.)**

Crocus chrysanthus is available in several varieties, all of which are referred to as snow crocus or golden crocus. ‘Cream Beauty’ is a strong grower that is primarily white with a white center. ‘Ladykiller’ is also white but with purple on the outside of the petals. ‘Advance’ is yellow inside but the outside is unique because the petals alternate creamy yellow and purple. Corms produce 1 to 4 flowers each in late February or early March. Like C. ancyrensis above, rabbits admire this species.

Crocus tommasinianus is a wonderful choice for several reasons. This species is the most pest-resistant crocus available. If you have lost crocus to rabbits or squirrels, this may be the choice for you. C. tommasinianus is also the most prolific grower. It will quickly naturalize to form masses of flowers. The most readily available variety is ‘Barr’s Purple.’ Its deep violet petals fade to a bright white center that is highlighted by bright orange stamens. It blooms almost as early as the above two species, usually in early March.

The most popular species is Crocus vernus or Dutch crocus. Unlike the previous species, one large flower with large gold stamens is produced from each corm. It is available in several colors ranging from white to stripes to purples. ‘Jeanne d’Arc’ is a bright white with large flowers. ‘Pickwick’ has large white flowers with dark lavender stripes inside and out. ‘Remembrance’ and ‘Flower Record’ are deep lavender and pale lavender respectively. Dutch crocus usually bloom from March to early April.

Fall is a perfect season for planting. Cooler weather means less heat stress for both plants and people. Plants are naturally becoming dormant and are far less susceptible to drying out and experiencing transplant shock. Fall is also the only season for planting spring-blooming bulbs and corms. Once the ground freezes, the opportunity is lost and you’ll regret not having these heralds of spring glowing in your early season garden. Crocus are relatively inexpensive and are available almost anywhere bulbs are sold. With minimal effort this fall, you can enhance your existing landscape and welcome spring with the bright blossoms of crocus.
