Flowering - April - June.

Habitat - Low woods, moist to wet ground, also cultivated.

Origin - Native to the U.S.

Lookalikes - Species of Prunus.

Other info. - This species is widely cultivated throughout Missouri but is found wild in only one southeastern county. It is an easy species to identify because of its showy flower clusters and blackish fruits. The fruits aren't really eaten much by wild animals, hence you will find them on the tree after the leaves have fallen and well into winter.
