Variety canadensis is cultivated and introduced in western states and in Europe. Typical var. canadensis is readily recognized; more hairy-stemmed plants are similar to var. hargeri, which usually has fewer disc florets. In eastern Canada and northern New England, the variety can be difficult to separate from narrow-leaved forms of S. lepida var. fallax if the array of the latter is not very leafy.

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

My Steuben County specimen is the only one I have that I regard as typical. The remainder are atypical forms that are nearer the typical form than the variety. My Steuben County specimen is from the mucky border of a lake and the remainder are from dry slopes.
