Baptisia australis, commonly called Blue False Indigo, is a long-lived, low-maintenance perennial prized for its upright habit and rich blue pea-like flowers in late spring to early summer. It forms a bushy, shrub-like mound of blue-green foliage, typically reaching 3 to 4 feet tall and wide. As it matures, it develops a deep root system, making it exceptionally drought tolerant. After blooming, it produces ornamental black seed pods that add fall interest. This native beauty fits beautifully into cottage gardens, prairie-style plantings, and pollinator habitats.
