Species of plum tree native to North America
Description[edit]
Prunus nigra, commonly known as the Canada plum or black plum, is a species of plum tree native to North America. It is a deciduous tree that typically grows to a height of 10 to 15 meters. The tree is characterized by its broad, spreading crown and its rough, scaly bark.
The leaves of Prunus nigra are simple, alternate, and ovate with serrated margins. They are dark green on the upper surface and paler underneath. In the autumn, the leaves turn vibrant shades of yellow and red, adding to the tree's ornamental appeal.
