Prunus nigra is one of the wild plums that are useful as a pollinator plum for some hybrid plums.
To get good crops of the wild plums, you need to have two of the prunus nigra so they can pollinate each other.

This Canadian Plum is little different than the American Plum and a few other very similar wild plum species in North America. The leaves of this species are 3 to 5 inches long by 1.5 to 3 inches wide with an abrupt narrow apex. The white flowers are about 1.3 inches in diameter in 3 to 4 flowered umbel clusters before or with young leaves. The orange-red plums are 1 to 1.3 inches long with yellow flesh inside and usually sweet. The native range is all around the Great Lakes, New Emgland, and a little of far southeast Canada.
