Autumn Jazz Viburnum

Viburnum dentatum 'Ralph Senior'

Plant Details:

Plant Type: Shrub
Plant Family: Adoxaceae
Plant Description: This large shrub grows in a vase shape up to ten feet tall. Flat-topped clusters of white flowers appear in late-spring and turn to dark purple fruits. The leaves are glossy and oval in shape with subtly serrated edges. It grows well in many soil types and can handle sun and shade. Prune in the spring after the flowers have gone.

Maintenance:

Maintenance Type: Shrub - Thinning
Plant Care: Shrub - Thinning (woody multi-stemmed plants that lose their leaves every winter and look best on older stems): Prune dead, diseased, or rubbing branches. Pruning is best done in late winter to early spring for most shrubs. With spring blooming shrubs, prune after the blooms are spent. Remove up to 1/3rd of the overall shrub, keeping older branches to build up a sturdy, permanent and picturesque framework. Keep in mind that these shrubs bloom directly on older wood or on shoots that come off old wood. Monitor for pests, diseases, or other ailments on a regular basis.
