Amorpha fruticosa

Several species of this Leguminous genus are hardy, and all come from North America. All are shrubs, but do not form hard wood very rapidly, the summer growth often dying back to within a few eyes of the base in winter.

They like light loam and a sunny position. Amorpha canescens, the Lead Plant, which was introduced in 1812, is the most ornamental here. It grows 2 to 3 feet high and bears pinnate leaves, covered with a dense, white tomentum, and terminal panicles of purple flowers with golden anthers.

The flowering time is August. Amorpha fruticosa, the False Indigo (southern United States), grows 8 to 10 feet high, and produces pinnate leaves and purple flowers. It cannot be said to be worthy of general cultivation. Other species are Californica, nana, and virgata.
