Viburnum – Distinguishing Snowball-type

As if gardeners didn’t have enough confusion sorting out plants which are not roses, but have rose in their name (rose of Sharon, rose moss, Confederate rose, etc), we also must distinguish between “snowball” viburnums.

Chinese snowball viburnum is Viburnum macrocephalum. It has huge (4 – 8 inch), round white flowers, borne on the ends of branches, in May

Japanese snowball viburnum is Viburnum plicatum. It has small (2 – 3 inch), round white flowers, borne two-ranked along the branches, in May.

European snowball viburnum is Viburnum opulus ‘Sterile’ or ‘Roseum’. Both have medium-sized (3 – 5 inch) blooms, borne at the ends of branches, and the leaves have three major lobes, much like a maple.

Fragrant snowball viburnum is Viburnum x carlcephalum. It has pink-white flowers which are very fragrant.
