The Story

Plant Bio

Clematis viticella, or Italian Clematis, is a deciduous, woody-stemmed climbing vine known for its vigorous growth and profuse, nodding, bell-shaped flowers. Viticella types are prized for their disease resistance (especially to clematis wilt) and for blooming on new wood, which allows for hard pruning in late winter.
