From Flora of Indiana (1940) by Charles C. Deam

This rare penstemon is local or infrequent in the "knobs" of a few counties along the Ohio River. It is found in poor soil in fallow fields and in open places on oak ridges. In 1932 it was found by Scott McCoy in rich soil in a field in the north part of Indianapolis, Marion County. It is difficult to reconcile these two widely different kinds of habitat for this plant.
