Propagating star magnolias

January 13, 2020   •   Leave a Comment

My star magnolia has some strange-looking pods where the buds for next year’s flowers appear. Out of curiosity, I cut one open to find orange seeds. Is this normal? Can I plant them and when?

The strange-looking pods are just your star magnolia’s (Magnolia stellata) fruit. They are completely normal and if left to open naturally, the orange seeds would have scattered on the ground. They could possibly germinate or be eaten by birds and other wildlife. Because the habit of a star magnolia is that of a rounded shrub, they are often grouped in a bank or hedge. They also can be limbed up and shaped to a small tree. The smooth gray bark is exemplary on mature plants. Although star magnolias are hardy to zone 4, their early spring flowering is at the mercy of weather. Late freezes and damaging spring winds take a toll on the delicate, white, and fragrant multi-petal blossoms. If your star magnolia is not a named cultivar, such as ‘Centennial’ or ‘Rosea,’ but the species, then the orange seeds could be viable and produce the same plant from which they came. However, the method most often used to propagate star magnolias is rooted stem cuttings. This ensures that the same plant characteristics will be generated. That is not to say collected seed will not germinate. For production propagation, stem cuttings and occasionally grafting are used to maintain and ensure consistency in genetics. The fact you cut the pod open could mean the seeds are not yet fully matured, and if planted before the ground freezes, may not germinate. If you want to experiment, plant the seeds in a protected area, in full sun and preferably in a peaty, organic, well-amended soil and see what happens.

Why does my columbine droop in my garden?

July 31, 2019   •   Leave a Comment

One of the most frequently used words to describe a columbine is “nodding.” The flowers are described as either nodding or upright, with a short, broad tube in front and backward projecting spurs. All columbines flower in spring or early summer and prefer rich soil in light to moderate shade with plenty of moisture. Many of the species are short-lived, especially if the drainage is poor. Aquilegia canadensis, a popular variety in garden centers, is native to eastern North America and found in moist, shady areas. The 1-1/2 inch flowers are nodding, appear in early spring, and continue blooming for about 6 weeks.

Why does your columbine droop and nod over in your garden? That is probably its nature. Planting a sturdier plant which blooms later, in front of the columbine, may help it stand up.

Getting rid of aggressive lily of the valley

December 1, 2017   •   2 Comments

One side of my backyard is overgrown with lily of the valley that came from my neighbor’s yard under the fence. I try digging them out in the spring when the ground is somewhat workable but I always seem to lose the battle. The soil is mostly clay and very hard to work with. I would like to get rid of them; any advice? B.P., Taylor

The creeping rhizomes of lily of the valley (Convallaria majalis) allow for rapid spread even in mediocre conditions. The clay may be hard for you to work in, but it hardly deters their persistent rootstock. Even a small piece of lingering rhizome can erupt in basal leaves. Lily of the valley spawns a love-hate relationship from gardeners in spring. They are one of the earliest fragrant white flowers, but once bloomed, the foliage browns out and dies back. In the meantime, the rhizomes grow and further invade areas of established lawns and gardens.

As they are in your neighbor’s yard, you will have to put a seamless metal (sheet roll aluminum) or stiff plastic barrier at least 18 inches down into the soil along the fence on your side where the plants grow. Stake it against the fence to prevent the rhizomes from pushing and bending the barrier. Diligently spade fork the rhizomes out and reduce the amount of shade and moisture in that area, which they prefer. Be aggressive in your approach by target spraying with an herbicide, such as glyphosate, any leaves that break the soil’s surface. Do not plant other plants in this area for a season while you do battle. Any compost or granular fertilizers you would use for your plants will only feed leftover rootlets. Perhaps you can negotiate with your neighbor to move the lily of the valley to another part of their yard where it won’t invade your yard. If not, practice patience and persistence to get rid of this invasive perennial.

Under the unsightly exterior, bruised fruit might contain better nutrition

May 4, 2016   •   Leave a Comment

An imprefect exterior of some fruits might be a sign of increased nutrition.
An imprefect exterior of some fruits might be a sign of increased nutrition.

NPR’s The Salt:

When orchardist Eliza Greenman walks through a field of apple trees and gazes upon a pocked array of blemished and buckled fruits — scarred from fighting fungus, heat and pests — she feels a little thrill of joy. “I’m absolutely infatuated with the idea of stress in an orchard,” says Greenman, who custom grafts and grows pesticide-free hard cider apples in Hamilton, Va. These forlorn, scabbed apples, says Greenman, may actually be sweeter.

In an unofficial experiment, Greenman tested scabbed and unscabbed Parma apples, a high-sugar variety native to southwestern Virginia, and found the scarred apples had a 2 to 5 percent higher sugar content than unmarred apples from the same tree. More sugar means a higher alcohol content once fermented, producing a tastier hard cider.

But she loves these ugly apples for another reason: They may be more nutritious and have a higher antioxidant content. Says Greenman: “I believe stress can help create a super fruit.”

George and Ellen Booth transformed a humble rock garden on their country estate in Bloomfield Hills into a serene Japanese garden.
George and Ellen Booth transformed a humble rock garden on their country estate in Bloomfield Hills into a serene Japanese garden.

On Sunday, April 24, 2016, 3:00 p.m., Dr. Kendall H. Brown presents “Cranbrook’s Japanese Garden in Context: Japanese-style Landscapes in America, Then and Now.” Co-sponsored by the Japan America Society of Michigan and Southwestern Ontario and hosted in partnership with Cranbrook Institute of Science (map), the lecture admission is free. Seating is limited; doors open at 2:30 p.m.

In 1915, Cranbrook founders George and Ellen Booth attended the Panama-Pacific International Exposition in San Francisco. Inspired by the exposition’s Japanese pavilion, they returned to Cranbrook and transformed a humble rock garden on their country estate in Bloomfield Hills into a serene Japanese garden. This lecture explores the fashion for Japanese gardens in America in the first decades of the 20th century, tracing their presence at worlds’ fairs, commercial sites, and great country homes. The presentation concludes by sketching how Japanese gardens are playing new, dynamic roles as sites of wellness and transformation today.

Dr. Brown is Professor of Asian Art History in the School of Art at California State University, Long Beach. He received BA and MA degrees in history and art history from the University of California, Berkeley, and a Ph.D. in art history from Yale University. Professor Brown is a leading figure in the study of Japanese gardens in North America. His book, Quiet Beauty: The Japanese Gardens of North America, is considered the definitive study in this field. This is his first lecture in Michigan.

Invasive-plant removal efforts to start this summer on Belle Isle

July 18, 2014   •   Leave a Comment

Efforts to remove invasive plant species on Belle Isle in the Detroit River begin this summer, thanks in large part to a $470,000 Great Lakes Restoration Initiative (GLRI) grant through the Environmental Protection Agency (EPA) to the Friends of the Detroit River (FDR), a nonprofit based in southeast Michigan.

The two-year project, which is currently in the planning phase, aims to control invasive plant species already present on Belle Isle—Michigan’s 102nd state park—and prevent additional invasive species through an outreach and education program that builds public awareness about invasive species and ways to minimize their introduction and spread on the island park.

“The Detroit River is a designated area of concern,” said FDR project manager Sam Lovall. “One of this project’s objectives is to remove the river’s top two impairments: loss of fish and wildlife habitat and degradation of fish and wildlife populations. We can assist in doing this through invasive plant species removal on the island.”

Improving habitat diversity
Four invasive plant species—including phragmites, which encompass 50 acres of the island, reed canary grass, purple loosestrife and Japanese knotweed—will be targeted for removal. “Invasive plant species can monopolize the landscape, growing in large groves, patches and stands that destroy the diversity of the habitat,” Lovall said. “The more plant species that live in an area, the healthier that area tends to be.”

Partnership makes it possible
The Belle Isle Conservancy—in partnership with the Department of Natural Resources—will oversee volunteer efforts, enlisting organizations such as the Greening of Detroit and Student Conservation Association to assist in removal of invasive species and evaluation of progress.

Conifers provide low-maintenance, year-round beauty

April 8, 2014   •   1 Comment

landscaping-with-conifers-and-gingkoGreat Lakes area gardeners might glance past this book due to the southern reference in the title (Landscaping with Conifers and Ginkgo for the Southeast). However, many of the plants described in it are applicable to the north as well. Consider this guide if you are interested in conifers, which are among the most beautiful and versatile of all landscape plants. They are low-maintenance and offer a variety of color, form, and texture year-round.

The authors have an authoritative command of their topic. Tom Cox, past president of the American Conifer Society, is the founder and owner of Cox Arboretum and Gardens in Georgia. John Ruter, Allan M. Armitage Endowed Professor of Horticulture at The University of Georgia, is a teacher, ornamental plant breeder, and author.

The result of years of research and horticulture experience, this compilation will help both novices and professionals build their conifer knowledge. Cox and Ruter present a wide variety of conifers and tips on growing, pruning, and preventing disease and pest problems. The Great Lakes reader can skim over specific southern growing advice. There is plenty else here to learn: the authors will teach you about conifers, no matter where you call home.

Identifying and controlling autumn olive

May 1, 2013   •   Leave a Comment

Michigan Department of Natural Resources:

Autumn olive is native to Asia and was introduced into the US in the 1830s. It was commonly planted for wildlife food and cover until its invasive traits became apparent. It produces abundant fruits that are widely distributed by birds and mammals. Like many non-native shrubs, it leafs out early and retains its leaves late in fall, shading out desirable native species and reducing species diversity. It is able to germinate and survive in shade as well as sun.

Autumn olive has root nodules that fix atmospheric nitrogen. As a result, it has the potential to degrade native plant communities that are adapted to low nutrient levels such as barrens and prairies. The resulting increase in nitrogen can promote the growth and spread of weedy species at the expense of low-nutrient adapted natives. In addition, it can increase stream water nitrate concentrations when it comprises a large portion of the stream bank vegetation.

Autumn olive does not appear to suffer significantly from herbivory by deer. In one study, it grew as tall outside of exclosures as it did within, while natives growing in the same places were much smaller when browsed by deer.
