A native of woods, savannas, and prairies from Ontario and Manitoba, south to Louisiana, Texas, and New Mexico, leadplant is a small shrub with silvery green leaves and bluish-purple flowers with bright orange anthers. White hairs cover the stems and leaves so that it appears to be covered with lead dust, giving it the common name leadplant. Its other common name, prairie shoestring, derives from the laced-shoestring look of the leaves and roots. Plants are deep rooted and so are very resistant to drought and recover quickly after a fire . Leadplant tolerates a wide variety of soils including ones that are nutrient poor and, in fact, adds nitrogen to the soil. Although it will tolerate some shade, it prefers full sun, and tends to sprawl in less light. Deer and rabbits love it.
