VIBURNUM :

Viburnum opulus, Snowball bush
Sometimes known as guelder rose, this viburnum is grown for the round panicles of tiny flowers that look like snowballs. The flowers start life green and turn creamy white as they age.

Viburnum tinus
An evergreen shrub, this viburnum is grown for its small, delicate, pal pink-flushed flowers in the early spring and for its blue berries in the late summer and early fall.
