The flowers of this prairie inhabitant have eluded me for years. Fortunately, I have friends with better timing.
Leadplant (Amorpha canescens) is indigenous to most of the Midwest and plains states, but it’s not one of those native plants you’ll often see along the roadside, like ironweed.
Although leadplant (sometimes called lead plant) is not rare or threatened, I’ve only found it in good-quality prairies, where it “tends to grow in clumps.” The Illinois Wildflowers website validates my experience: “The presence of Leadplant is a sign of high quality habitat. Because of its deep roots, recovery from fire is very good.”
Speaking of which, the Friends of the Eloise Butler Wildflower Garden website notes that “The alternate name ‘Devil’s Shoestrings’ comes from the deep roots which farmers were never able to plough out.” The more common name of leadplant comes from “the whitish or hoary color tinge from the fine leaf and stem hair.”
