Management:
Timber removal would be detrimental. Exotic pest plants are a threat to this species and should be removed. Avoid creating access to the site through trail or road construction.

Midwestern endemic; found in the Ohio- Mississippi R. junction in Illinois, Kentucky, Tennessee, Arkansas, and Missouri. Wabash R. in Indiana and Illinois. Reports from Eastern states (Maryland, Virginia, and North Carolina) as well as D.C. are now referred to a different species, Phacelia covillei, but are considered to be P. ranunculacea in many references.
