So unusual! 1 1/2" star-like flowers in violet-purple with white centers that have a very fragrant vanilla scent. Bloom from July to September. Rubromarginata is a vigorous climber with dark green leaves.
May also plant where it can sprawl over and through shrubs or use as an effective groundcover. Gracefully meandering over fences, trellises or through shrubbery, Clematis supply vertical interest. Every perennial garden should have at least one of these incredible vines.
