Description

Baptisia australis, or Blue Wild Indigo, is a 3-5 foot, hardy, long-lived perennial legume for full sun to light shade and well-drained medium moist soils. The attractive, dark blue flowers and glossy blue-green trifoliate leaves on Blue Wild Indigo bloom from May to June. All Baptisia species are nitrogen-fixing legumes, meaning they have a symbiotic relationship with the Rhizobium bacteria that allows them to utilize atmospheric nitrogen.
