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

Local to frequent in the lake area where it grows mostly in moist, alluvial soil in woodland, along streams and fences, and on the borders of interdunal swamps along Lake Michigan. Local in southern Indiana. [The pubescent variety demissa] is frequent on the crests of the high dunes facing Lake Michigan and on the crests of the low dunes along Lake Michigan west of Gary. Here it replaces the [full] species [Prunus virginiana]. I have not found it except near the lake. I found a plant about 2 inches in diameter in a tamarack bog in the Pokagon State Park, Steuben County. I also found a few specimens in Lagrange County in very sandy soil on the high bank of Pigeon River about 2 miles southeast of Mongo. In cultivation this variety soon forms close colonies.
