False indigo Interesting Notes

The genus name comes from the Greek word "bapto" which means "to dye" because some of the darker flowered species were used as dyes.

This selection emerged from a cross of Baptisia [[tinctoria x alba] x open-pollinated, probably australis] developed by Dr. Jim Ault at the Chicago Botanic Garden in Glencoe, Illinois. The plant boasts an upright, vase-shaped habit with extremely long inflorescences bearing deep blue-violet flowers. The plant has two intermingling bloom cycles within its blooming season. The first cycle produces long primary inflorescences up to 24" long. The second cycle produces blooms on secondary branches with inflorescences up to 5" long. Having two consecutive bloom cycles helps this plant stay in bloom for nearly the entire month of June — a good seven to ten days longer than most other Baptisia. Mature plants measure to 3½' to 4' wide and 4' to 5' tall. Long-lived and drought tolerant. - Chicagoland Grows®

Medium vigor for a false indigo. A mature plant tends to have fewer stems than more vigorous Baptisia such as B. australis and B. 'Twilite'.
