The Blackhaw viburnum (Viburnum prunifolium) is a species of viburnum native to Eastern part of North America. It is a multi-stemmed, deciduous shrub and typically grows 12-15 feet tall with a spread of 6-12 feet. Non-fragrant white flowers in flat-topped cymes appear in spring. Ovate, finely toothed, glossy dark green leaves (to 4″ long) turn attractive shades of red and purple in fall. Fruits are edible and may be eaten off the bush when ripe or used in jams and preserves. Native Americans and American slaveholders used a decoction of Black haw to treat menstrual cramp and to prevent abortions.
