Prunus virginiana 'Shubert'

Prunus virginiana, commonly called bitter-berry, chokecherry, Virginia bird cherry, and western chokecherry (also black chokecherry for P. virginiana var. demissa), is a North American species of bird cherry (Prunus subgenus Padus). Forming a tree generally up to 6 metres (19+1⁄2 feet) tall, the leaves are oval, green, and smooth, with racemes of white flowers and red to black drupes. The unripe fruits are toxic, as is the stone and much of the plant, but the ripe fruits are edible, being part of Native American cuisine.
