Grow this floriferous form of Italian Clematis when you are looking for summer into fall color in a vine that isn't going to take over the world. 'Etoile Violette' is a vine that extends 10-12' in length, forming a thicket 5-6' wide. Royal purple 6 petaled blossoms with contrasting golden yellow stamens are about 3.5" wide. Once established, this Clematis can be cut back to 12" in late winter to control tangled congestion. Clematis want a rich well drained soil that can be supplementally watered during dry spells.
