Nannyberry is grown as an ornamental. One cultivated variety with purple stamens is spectacular! Another individual, growing against a friend's house, has been cut off nearly annually for at least 30 years and keeps coming up. Wonder why?
The bark and leaves of nannyberry were used by Indians for a variety of herbal medicines. The purple berries are edible, but with thin flesh and not much taste. The berries are food to many birds and animals, particularly songbirds.
