15 shade-flowering perennials for fall

15 shade-flowering perennials for fall

This year, add some fall perennials that will extend the blooming season, even in the shadiest parts of your landscape. You might be surprised to learn how many woodland plants bloom in fall—even in shade—and produce their best blooms while others dwindle. It’s nature’s way of making sure birds, bees, butterflies and other pollinators are ready to migrate, hibernate or face the coming winter.

“I think people look at the end of summer and think the garden should be cleaned up and closed,” says Mark Dwyer, owner of Landscape Prescriptions and director of the Healing Garden in southern Wisconsin. “But prolonged flowering, whether in sun or shade, is vital to supporting our native pollinators.”

We asked Dwyer and horticulturist Margaret Beckoff of Pennsylvania in Bucks County, Pennsylvania, to recommend their favorite fall-blooming perennials.

Native to the central and southeastern United States, it is also a good food source for pollinating insects that have evolved with it and will recognize it as such. “Fall can be a difficult time for pollinators to find resources,” Bekoff says. “So it’s a good idea to provide plants in the garden that are native to your area of ​​the county so they can have a good meal before winter comes.”

Flowering begins in late summer and can extend until the first frost. Sharply cut foliage provides extra interest in fall landscapes, Bekoff says.

It is a member of the mint family, and it spreads slowly. “I haven’t regretted my farming at all,” Dwyer says.
