Amorpha fruticosa is a deciduous shrub with a dens growing habit. typically wider than tall, it can reach a mature height in excess of 12'. Although the individual flowers are small, they are clustered to form dense, showy purple spikes up to 8" long, and pleasantly fragrant. The leaves are compound, pinnate, with up to 35 oval to oblong gray-green leaflets.
False indigo is very easy to grow in full to part-sun. It is adaptable to a wide range of soil types and conditions ranging from dry to bog-like. It can spread aggressively by suckers and by seed in rich, moist to wet environments, making it an excellent choice for stream bank stabilization and erosion control. Zones 4-10
Propagate by softwood or hardwood cuttings. Seeds will need to undergo scarification to improve otherwise poor germination rates. Suckers can also be transplanted in early spring.
Amorpha fruticosa is very attractive to pollinators, and is a host plant for several species of butterflies, moths, and beetles. It is highly deer resistant.
