Although the individual flowers are small, they are clustered to form dense, showy purple spikes up to 8" long, and pleasantly fragrant.

Cultivation

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
