Introduced from farther south, two collections from fencerows or near old homesteads appear to be this species, first collected in Leelanau Co. in 1974, though only flowering specimens are known. This is a thicket-forming shrub or small tree with small, narrow leaves compared to our other plums. These collections were reported in Michigan Flora as P. cerasifera, the Eurasian Cherry Plum, which differs in having larger flowers on longer pedicels, usually borne singly. A vegetative specimen of P. cerasifera is known from Michigan, collected by J. R. Rohrer in 2007 in Cheboygan Co., but it was noted as “possibly planted.”
