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
