False indigo (Baptisia australis) is a large, upright long-lived perennial flowering plant in the family Fabaceae. Commonly known as blue wild indigo or blue false indigo, it is a perennial herb native to much of central and eastern North America. The flowers were once used by Native Americans and early European settlers as a dye.
The plant may grow to a height of 1 to 1.5m, and a width of 0.6 to 1m. The grey-green leaves are arranged alternately, and are further divided into clover-like leaflets that are wider towards the apex. Flower spikes appear in early summer. Emerging at the pinnacle are short, upright terminal racemes with pea-like flowers that vary in color from light blue to deep violet.
Medicinal Uses
It was used by European herbalists and is thought to stimulate the immune system to purge any infections. Some ailments it is used for include ear, nose, and throat infections.
Please Note: The plant is poisonous to both animals and humans, when ingested in large quantities. Side effects of ingesting blue indigo may include vomiting, diarrhea and gastrointestinal spasms. The plant should only be used medicinally under the supervision of a trained professional.
