History
Baptisia alba inhabits moist to dry prairies, savannas, and glades from New Jersey south to Florida and west to Texas. Linnaeus described it as Crotalaria alba in 1753, and the genus Baptisia was later established by Ventenat in 1808. Cherokee and Creek peoples used small amounts of the bitter root to treat toothache, inflammation, and as a purgative.
Colonial dyers occasionally used it like B. tinctoria for blue coloring, though with poorer results. It entered Victorian perennial borders through trade between American and European nurseries in the mid-1800s.
Modern breeding, including Jim Ault's 'Prairieblues' series from Chicago Botanic Garden, has crossed it with B. australis and B. sphaerocarpa to produce hybrids such as 'Twilite Prairieblues' and 'Solar Flare'. Long-lived plants develop deep taproots that can sustain the plant for 50 years or more. Increasingly grown in American native plant gardens as a structural alternative to non-native shrubs.
