Amorpha canescens

Amorpha canescens (Leadplant, Leadplant amorpha, Prairie shoestring) is a 30–90 cm (0.98–2.95 ft) tall deciduous shrub in the Pea family (Fabaceae) that is native to North America. It has very small purple flowers with yellow stamens which are grouped in racemes. The flowers bloom in early July. The compound leaves of this plant appear leaden (the reason for the common name "leadplant") due to their dense hairiness. The roots can grow deeper than 1.2 meters (3.9 feet). This plant can be found growing in well drained soils of prairies, bluffs, and open woodlands.
