A native North American perennial with upright growth and striking blue-purple flowers in late spring. Drought-tolerant once established, it's excellent for borders and attracts pollinators.
Why grow it
Baptisia australis offers reliable summer color from a long-lived perennial that requires minimal inputs once established. Compared to hybrid delphiniums and lupines, wild indigo is notably more drought-tolerant and disease-resistant in most climates, making it a lower-maintenance choice for naturalistic plantings. It fixes nitrogen in poor soils and provides early-season nectar for native pollinators, particularly bees.
Watch out for
Young plants are slow to establish and may take 2-3 years to reach full size and flowering capacity. The seed pods persist well into winter (an asset for seasonal interest) but will self-seed readily if allowed to mature, which can result in volunteer seedlings beyond the original planting area. Plants dislike being divided or transplanted once mature, so siting decisions should be considered permanent.
