'Nantucket' Viburnum came from a cross made by the late Dr. Egolf between V. x 'Eskimo' and V. macrocephalum f. keteleeri at the National Arboretum in 1988. For some reason this excellent plant only recently got the notice it deserves. The large white ball-shaped flowers appear in April and are mildly fragrant. The neat dark green leaves are semi-evergreen, and Viburnum 'Nantucket' has shown excellent heat resistance, according to Dr. Michael Dirr. The habit is somewhat upright, and would be effective as a hedge as well as a specimen plant.
