Viburnum plicatum f. tomentosum

Viburnum plicatum f. tomentosum 'St. Keverne'

A more upright form of doublefile viburnum growing 10-12' tall but still maintaining a horizontally tiered habit.  Raised at St Keverne, Cornwall, England.  Flowers are a flat-topped to somewhat umbrella shaped cyme with a sterile outer ring of white flowers and an inner circle of smaller fertile florets.  On a personal note, some of the petals of the larger ray flowers are curved upward, giving the appearance of white butterflies perched on the inflorescence.  Fruit is small, red, but sparse.  Green foliage has deeply furrowed veination, which turns a purple-red in the fall.  Zone 5

USDA Hardiness Zone:



Unfortunately, this plant has not found its way into the trade or the home garden.  We have found this plic. f. tom. to be one of the hardiest of the species.  We have overwintered this cultivar in its pot above the ground with no winter protection whatsoever with no dieback.  This would be a great selection for those in a true Zone 4 that have not been successful with any other plic. f. tom. form.
