The U.S. National Arboretum presents Viburnum x burkwoodii 'Conoy', the image of excellence. This compact, evergreen viburnum deserves a place in every landscape. The high gloss of the small, dark green leaves is a perfect backdrop for lightly fragrant, white flowers in late April. The abundant flowers are followed by a colorful red fruiting display beginning in late August and lasting for 6-8 weeks. Cold winter weather gives the foliage a maroon tinge. You'll agree, 'Conoy' is a winner - year round!
Recognition: The Pennsylvania Horticultural Society Gold Medal Plant Award, 1997.
