This large perennial becomes a bushy mass of sky blue foliage topped with spikes of indigo blue pea-like flowers in early summer. After flowering deep purplish black seed pods develop and remain attractive until fall. Baptisia australis is easy to grow and will thrive with little maintenance and is very long-lived and drought tolerant once established.

- Culture Notes
- Blue indigo grows best in full sun with well-drained soil and is tolerant of sandy and clay situations. Rich organic soils and heavy fertilizing can make it floppy and growing it in lean and poor soils will produce a more compact plant. Once established it is drought tolerant. This is a very easy perennial with almost no health issues, but it is slow growing and resents being disturbed so provide it with plenty of room in the garden.
