Baptisia tinctoria (L.) R. Br.
Horseflyweed, Yellow Wild Indigo
Fabaceae (Pea Family)
Synonym(s): Baptisia gibbesii, Baptisia tinctoria var. crebra, Baptisia tinctoria var. projecta
USDA Symbol: BATI
USDA Native Status: L48 (N), CAN (N)
Smooth, bushy perennial with numerous few-flowered, elongated terminal clusters of yellow pea-like flowers.
Widely distributed, Wild Indigo often increases in burnt fields. Some 15 other species are found in eastern North America, including numerous yellow species farther south and some white or creamy ones. Blue False Indigo (B.australis), which has upright racemes of blue flowers and sap that turns purple when exposed to air, has escaped from cultivation northward to New York and Vermont. The genus name, from the Greek baptizein ("to dye"), refers to the fact that some species are used as an inferior substitute for true indigo dye.
