Amorpha canescens

Leadplant (Amorpha canescens) exhibits a unique display of both foliage and flowers. Spikes of iridescent purple flowers appear atop the delicate silver-gray foliage in the heat of mid-summer. Extremely long-lived, this is one of the few true shrubs of the prairie. Leadplant's deep taproot makes it extremely drought tolerant. Thrives in any well-drained soil.
