Genus - Baptisia
Baptisia is also called Wild Indigo or False Indigo. It contains over 34 species. Their flowers are pea-like in appearance. The name is derived from the Greek "Bapto" meaning to dip. This refers to the dipping of cloth in the Baptisia dye.
When Europeans in the 1700's had trouble getting true Indigo dye they paid colonists to grow Baptisia to use as a substitute. Hence the common name of false indigo
Baptisia has excellent deer resistance.
