Blue False Indigo
Best resilient perennial for vibrant, low maintenance garden displays.
The native Blue False Indigo (Baptisia australis) is a long-lived perennial that was historically used in early American gardens as a source of blue dye. It produces deep indigo blue, pea-like flowers in spring above attractive blue-green foliage. This hardy plant thrives in moist but well-drained soil, preferring part shade to full sun. Once established, it is drought tolerant and attracts butterflies, making it a valuable addition to borders or wild gardens. The showy seed pods are also useful for dried arrangements.
