- Description
-
Italian clematis is a deciduous or evergreen, perennial vine in the buttercup family (Ranunculaceae) native from southern Europe to Asia. The specific epithet is Latin for “small vine.”
Plant in full sun but provide shade for the roots. Good draining moist soils with neutral to alkaline pH are ideal. Italian clematis blooms on new wood so severely prune it back to about 1 foot tall in late winter or early spring (Type 3). Propagate by layering or stem cutting. This species is highly resistant to clematis wilt.
Italian clematis grows rapidly to a height of 10 to 15 feet and a width of 3 to 5 feet. It has a long bloom season from summer to fall, boasting showy deep purple flowers with many yellow stamens. The flowers are followed by attractive small, dry fruits each with a silky, feathery tail.
This plant is a great climber and can be trained to grow on an arbor, along a fence, rock wall, or other vertical space. It can spread along the ground in a woodland or naturalized area, spill out of a container placed on a patio, or provide a backdrop in a cottage or English 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.
