Midnight Prairieblues? was selected in 2003 by Dr. Jim Ault of the Chicago Botanic Garden, Glencoe, Illinois, from an open-pollinated seedling population. The seed parent was a hybrid of [Baptisia tinctoria x Baptisia alba]. The pollen parent is thought to be Baptisia australis. The selection features traits from all three parent species. 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?.
