About

Prunus nigra, the Canada plum, Canadian plum, or black plum, is a species of Prunus native to eastern North America.

Where it grows

It can be found from Nova Scotia west to Minnesota and southeastern Manitoba, and south as far as Connecticut, Illinois, and Iowa. It is endangered in Ohio. Isolated populations are present along streambanks in Saskatchewan and Alberta, along Lake Timiskaming in Northern Ontario, and along the Maine-New Brunswick border.

Uses

The fruit is somewhat sour, clingstone, and very juicy. It can be eaten raw when fully ripe or cooked and made into pies, preserves, and jellies. Dried, these plums were a popular winter staple of indigenous peoples. French explorer Jacques Cartier remarked in his journal that he was presented with dried Canada plums by the St. Lawrence Iroquoians in his first expedition to Canada.
