The fruit, which is sweet and edible, is about half an inch long, bluish black, covered with a bloom, and ripens in early autumn. It contains a somewhat flattened stone.

The bark is reddish-brown, very rough on old stems. The branchlets are red at first, and then green, finally dark brown tinged with red. The winter buds are coated with rusty tomentum.
