Description

Western false indigo is native throughout much of North America, found usually near a water source. It grows aggressively in an open, fountain form with many fronds of compound leaves. The intricate ornate flowers of purple, yellow and orange cover the upper growth with generous splays. After winter dormancy, western false indigo will return spring after spring in a widening clump. This may be (and may need to be) controlled with pruning of the fibrous roots during winter dormancy. Western false indigo prefers a sunnier situation than its close relative California false indigo, Amorpha californica.
