Black Haw Viburnum: Tree or Shrub?
Black haw viburnum (Viburnum prunifolium) can easily be used as a large, multi-stemmed shrub or small tree in the landscape. Blackhaws are some of the most twiggy and dense members of the Viburnum family. A slow grower, black haw reaches about 15 feet in height and 10 feet in width at maturity. Hardy to Zone 3, it has an oval growth habit when young, but will become more rounded, spreading, or irregular as it ages. It can be utilized in larger landscape foundation plantings, as informal hedges and in woodland settings.
