Tall Blue Indigo (Baptisia australis)
Legume Family
This nitrogen-fixing legume produces striking spires of pea-like indigo-blue flowers in late spring to early summer, followed by distinctive black seed pods that mature to a dark, metallic gray. Its blue-green, trifoliate leaves grow on sturdy stems, forming an attractive, bushy, shrub-like habit, 3-4 feet tall and wide. Deep-rooted and highly resilient, it thrives in full sun and well-drained soils, exhibiting excellent drought tolerance but is difficult to transplant. Whether planted singly or in groups, it adds rich texture to the landscape. Though it takes 3-4 years to establish, it rewards patience with a hardy, low-maintenance, and deer-resistant presence.
