Racemes of little white flowers cover the trees in the spring, followed by tiny but delicious black cherries. Similar to the Choke Cherry (Prunus virginiana), but with narrower, glossier leaves; and the Black Cherry grows into a large tree with ragged bark, whereas the Choke Cherry seldom exceeds a large shrub and has smooth bark. This tree was growing in Bird Park, Mount Lebanon.
For a description of the species, see the Prunus serotina reference page.
