COMMON BUTTERCUP, TALL BUTTERCUP
R. W. Smith
Roadsides, fields, clearings, shores, moist thickets. A native of Europe, where it is also weedy. Long established; first collected in 1845 in Macomb Co.
An occasionally cultivated "double" variant, with all the floral parts converted to petals, rarely escapes; collections of this form have been made in St. Clair, Mackinac, and Washtenaw Cos.
