Chokecherry
Prunus virginiana
Chokecherry earns its name honestly — the raw fruits are famously astringent — but as a wildlife tree and native shrub for difficult sites, it is nearly without equal across the northern half of the continent.
Prunus virginiana grows as a large shrub or small tree to 30 feet, ranging from zone 2 through 6 and native to an extraordinary breadth of North American habitats: woodland edges, ravines, slopes, thickets, and open fields. In spring, white flower clusters line the branches and support pollinators. The fruits that follow are among the most important in the native ecosystem — bears, moose, coyotes, and bighorn sheep browse the foliage, birds consume the fruits in quantity, and small mammals collect the seeds. It is a plant that feeds things.
In garden use, its tendency to form thickets via underground runners needs to be factored in — this is a plant for the back of a large property, a naturalized woodland edge, or a wildlife planting rather than a confined border. Damaged foliage and wilted leaves are toxic to livestock and humans, a fact worth knowing before planting near a pasture. Branches can be brittle in ice storms. But for cold-climate gardens where ecological generosity matters, Chokecherry is hard to argue with.
