What Makes Me Special?

Landscape Use

Borders, foundations, mass plantings, commercial landscapes, naturalized plantings

Origin

Selected by Ralph Synnestvedt, Sr. of the Synnestvedt Nursery Company, Round Lake, Illinois.

Pruning

Viburnums flower in spring, so if they need any shaping or to have dead branches removed, be sure to do that before August, or right after flowering in the spring. If you want to have viburnum fruits, do not prune. Branches you prune after flowering will not produce fruits.

Propagation

Softwood Cuttings
