Leadplant is an upright, rounded shrub, native to the Midwest, that does well in dry sandy to clay soil; the attractive gray-green foliage adds nice contrast in rock gardens. The purplish-blue flower spikes in June and July serve as a host to caterpillars, as well as a nectar source for butterflies, and a food source for birds.
