Viburnum opulus 'sterile'
Caprifoliaceae
This vigorous deciduous bushy shrub is fully
hardy from zones 4-8. It originated from Europe and Northern and Western Asia. It
has an upright growth when young becoming spreading and branching with age. The
height can reach from 12-15' tall and equally wide. The bark of the shrub is a
gray to gray-green color. Leaves are light to dark green, 2-5" long with a
orange tinge in late summer to autumn. They are five lobed and resemble maple
leaves. The flowers are globular snowball-like cluster of florets. This variety
is unique in the fact that it is one of the non-fruiting Viburnums.
This
shrub can tolerate a range of soils from alkaline to acidity, dry to
waterlogged. Grows best in full sun but can tolerate sun medium shade. Can be
left unpruned to form a woody shrub but can be pruned to ground each year to
keep from becoming woody. Can be found sold in several different forms i.e.
B&B, container grown. Best planting heights are 2-3". It has no serious disease or pest problems
however it usually outgrows the area it was planted in.
