Wetland indicator: Facultative Upland, Facultative

Can grow to 30' high and almost equal spread, sometimes occurring as a tree with a few main trunks. Birds devour the fruits as quickly as they ripen. Although reputed to be edible, the fruit is so astringent that it is nearly impossible to swallow, hence the name "Choke Cherry".

Several purple-leaves cultivars are available, such as 'Schubert', 'Canada Red', 'Mini-Schubert', and 'Robert'. Seedlings of 'Schubert' often retain the purple foliage trait, as can be seed in the last image. Note the loss of pigment on the youngest growth which occurs in warm weather. Fall color can be a good purple-red but leaves tend to drop too quickly for it to be effective.
