Serviceberry, Amelanchier intermedia, escaped from cultivation in eastern Ontario.

Although not generally recognized as a cultivated plant, Amelanchier intermedia is widely cultivated in eastern Ontario under the incorrect name, A. canadensis. Wild plants referable to A. intermedia in old fields south of Ottawa are likely to be escaped from cultivation. Amelanchier intermedia likely originated as a hybrid involving A. canadensis and A. laevis. A key to the Canadian species of Amelanchier with glabrous ovaries is provided.
