The rounded, stiffly branched habit of Blackhaw viburnum reminds you of a Hawthorn. Other common names are Sloe, sloe-leaved viburnum, stagbush, shonny. It can be grown as a small tree because plants attain a height of 12 to 14 feet. The dark green, glossy, leathery leaves turn a dark reddish to purple in the fall. Creamy white flowers are borne in flat-topped flower clusters during May. The fruit turns blue-black at maturity. The fruit, which is sweet and edible, is nearly half an inch long, bluish black, covered with a bloom, and ripens in early autumn. It contains a small and somewhat flattened stone. The mature fruit make good preserves. The leaves are small enough that they don't pose a raking and cleaning problem. Birds frequent this shrub for feed and shelter.
