This is one of a handful of "prairie plants" in NC -- species whose main range lies in high pH prairie-like or glade-like habitats west of the Appalachians -- and one of the state's most beautiful wildflowers. Read more at Vascular Plants of North Carolina.

The “aberrans” entity has been lumped into either “minor” or “australis,” it has been treated as a variety of both “minor” and “australis,” and it has been judged to be “the first of the trio to diverge independently”, per Weakley's Flora (2022)

For an in-depth treatment, peruse A monograph of the genus Baptisia (Larisey, 1940).
