Description

Italian clematis is a deciduous or evergreen vine in the Ranunculaceae (buttercup) family native to Europe and Asia. 

Plant in the full sun but provide shade for the roots.  Good draining moist soils are ideal.Italian clematis blooms on new wood so severely prune it back to about 1 feet tall in early spring. 

Italian clematis grows slowly to a length of 10 to 15 feet and a width of 3 to 5 feet.  It has a long bloom season from summer to fall boasting deep purple flowers with many yellow stamens.  The flowers are followed by attractive small, dry fruits (each with a silky-plumose tail). 

This plant is a great climber and can be trained to be a backdrop and even grow on an arbor.  Its twisting petioles and showy flowers looks attractive planted along a fence, in a woodland area, or in a formal English style garden. 

Insects, Diseases, and Other Plant Problems: Aphids may attack young growth.  Slugs, snails. and voles may damage young roots. Plants are susceptible to powdery mildew but are highly resistant to clematis wilt.  This plant can cause contact dermatitis so use gloves when handling.
