I think it's supposed to be Etoile Violette.

U r right. I found it at Spring Hill Nursery. Thank you for that. Maybe u could tell me how to propagate it. I can do just about anything but clematis. And I'm still hinting for Flammula its sister got found I need the white one. Thank you

The nurseries that are advertising/selling it under that name are of very questionable quality. Don't purchase from them. Most reputable clematis specialty nurseries - the ones discussed at length in the Clematis forum - sell 'Etoile Violette'. It is a very popular cultivar.

Clematis can be propagated by cuttings or layering. Since the vast majority sold are hybrids, growing from seed will produce mixed results. They can sometimes be divided as well but only with more mature, multistemmed vines and even then with caution.

Cathy, I highly recommend Brushwood Nursery. I got many plants from them in the past (in a different zone :) and they were outstanding. All my best performers came from Brushwood.

Marketing a variety that will cover an area with 'wall of flowers' ... This fast-growing perennial vine will easily cover your garden wall or trellises for screening and privacy—or will cover the ground in border and rock gardens. Its lush leaves are a beautiful green palmate shape with a pinnate structure, arranged opposite of each other along the stems. As for its blooms, the richly purple 3" flowers contrast perfectly with its green foliage. While the petals can range in color from bright purple to almost black, the centers will always have a cream-colored "eye" of stamens. It grows best in rich, well-drained soil in full sunlight or partial shade, and can grow between 5-10' tall! Clematis 'Etoile Violette' .. My recommendation is to always check on size of roots/pot sold. I've never had any luck with dime Store Plugs in plastic bags in big box stores. I buy from Bakery Betty on Etsy - big roots.
