Multiyear Study of Factors Related to Flowering Phenology and Reproductive Yield of Baptisia Alba in Northeastern Illinois (Report‪)‬

INTRODUCTION The white wild indigo, Baptisia alba L. (Vent.) (= B. leucantha), is a widely distributed legume in prairie and open woods of the Midwest (Swink and Wilhelm 1994). The perennial blooms prolifically during late spring, producing a central raceme and often 10 or more satellite racemes. In northeastern Illinois, the location of the current study, most B. alba bloom during a two-week period in June. However, some plants bloom much later, beginning after mid July.
