Discussion

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.
