Blue Wild Indigo (Baptisia australis)

Blue Wild Indigo (Baptisia australis), also known as False Indigo, is a striking, long-lived perennial admired for its tall spikes of deep blue flowers that bloom from late spring to early summer. This drought-tolerant variety adds architectural interest to garden beds, borders, and native plant landscapes, while its blue-green foliage and ornamental seed pods provide multi-season appeal.
