Viburnum nudum

Viburnum nudum 'Winterthur'

A medium sized shrub growing 6' after 10 years but reported sightings of 8' and slightly narrower.  Similar to and often confused with V. cassinoides but the foliage is more lustrous and waxy green.  Foliage is elliptical and olive to dark geen above and lighter below.  Selected by Winterthur Garden of Delaware.  One of the later blooming viburnums with creamy-white, flat-topped flower clusters in late June-early July.  Fruit clusters start white, turning to hot pink and red, and maturing to dark blue.  Fall color is a breathtaking wine-red to reddish-purple.  Attractive black bark adds winter interest.  Dislikes alkaline soils.  Zone 5
