Chinese Snowball Viburnum produces an enormous quantity of lovely sterile blooms. The snowball flowers hang from the branches in May to June, changing from lime green to white as they mature. Viburnum macrocephalum makes a large vase-shaped plant which bears a close resemblance to a Pee Gee Hydrangea when in bloom. The green dentate foliage is attractive and disease resistant and somewhat pubescent. Since the flowers are sterile, there is no fruit. Pruning for a tighter shape is best done just after the bloom period. A native of China.
