Amorpha canescens

Lead Plant, Devil's Shoestrings, False Indigo, Downy  Indigo. Dense spikes of tiny deep purple flowers in mid to late summer. Fine grey-green aromatic leaves. Tough deep roots give it its second common name. Small shrub in mild winters, herbaceous in harsh winters. Long-lived, drought tolerant, flowers in summer.  New for me.  Still small but growing.
