Blue False Indigo (Baptisia australis) is a large bush-like perennial, with dense clusters of deep blue flowers on long upright spikes. In its first few years this long-lived plant develops mostly below ground. After the first two seasons the blooms are increasingly showy as the plant matures. Attractive bluish-green foliage provides a good backdrop to other flowering plants. An excellent specimen plant for formal designs, Baptisia australis is beautiful in naturalized settings, as well. Because of its wide, branching form, generous spacing is advisable. The tough rootstock can be divided in fall or spring when the plant is dormant.

Blue False Indigo is a host plant for the Frosted Elfin, Wild Indigo Duskywing, and Hoary Edge butterflies.
