Softhair Marbleseed: A Hardy Native Wildflower for Low-Maintenance Gardens
If you’re looking for a tough, no-fuss native wildflower that won’t demand constant attention, softhair marbleseed (Onosmodium bejariense var. hispidissimum) might just be your new gardening friend. This perennial forb may not win any beauty contests, but it brings authentic native charm and ecological value to gardens across much of eastern and central North America.
What is Softhair Marbleseed?
Softhair marbleseed is a native perennial forb—essentially a non-woody flowering plant that comes back year after year. True to its name, this plant sports distinctively hairy (hispid) stems and leaves that give it a somewhat coarse, textured appearance. Don’t let the soft in its common name fool you; those hairs can actually feel quite rough to the touch!
As a member of the borage family, softhair marbleseed produces small, tubular white flowers arranged in clusters. While the individual blooms are modest, they collectively create an interesting display that native pollinators absolutely appreciate.
Where Does It Grow Naturally?
This hardy native has quite an impressive range, naturally occurring across a wide swath of North America. You’ll find softhair marbleseed growing wild from southern Canada down through much of the eastern and central United States, including Alabama, Arkansas, Connecticut, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Missouri, New Hampshire, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Wisconsin, plus Ontario and Quebec in Canada.
