Chokecherry (Prunus virginiana) is a suckering large shrub or small tree common over much of the United States. Foliage is dark green above and gray-green beneath, turning shades of yellow and orange in the fall. Chokecherry has attractive white flowers that grow in long clusters in mid-spring and give way to pea-sized red berries that will darken to purple or black in the late summer. These berries are tart and bitter, but when very ripe at the end of the summer can be processed into jams, jellies, pies, sauces, etc. They are also loved by birds and other animals. Add as a specimen tree or shrub to garden beds, plant in woodland or shade gardens, or use as a privacy hedge or screen. It is tolerant of urban pollution.
