Baptisia (False Indigo)

Baptisia australis

Baptisia is a long-lived native perennial that forms a substantial shrub-like mound — spikes of pea-like flowers in deep indigo blue, followed by attractive charcoal-black seed pods that rattle in the wind. Once established, it lives for decades and is virtually indestructible. 'Decadence' series offers yellow, purple, and bi-color varieties. Slow to establish but worth the wait.
