One of my favorite clematis. Vigorous, floriferous, long-blooming, and, like all viticella hybrids, resistant to clematis wilt.

I don't find this to noticeably fragrant.

Clematis and tomatoes are two exceptions to the usual rule, and are best planted 6 inches deeper than the soil level in the pot. This protects the stem bases from mechanical damage, and helps prevent clematis wilt, whose fungus enters where there's damage. It also helps keep the roots cool and more evenly moist.

This is the best clematis EVER, at least in our far northern Michigan climate. It's tough, hardy, undemanding, and - best of all - beautiful. It just keeps blooming. Once established, it's drought-tolerant. Everyone who sees it in my garden wants it. Highly recommended.

I fell in love with this at a garden tour in Bossier, Louisiana. I went home and put two tomato cages together to make a Betty Corninng 'Shrub" in my " blue" bed.- Ginger gaia

I love this clematis for its delicate fragrance, color and shape. It also blooms all summer for me. I planted it near my side door so I can sniff the flowers every time I go in and out of the house.

This selection was discovered in the USA by Betty Corning in 1932. It is thought to be a cross between C. crispa and C. viticella. It appears most like the viticella parent but has some fragrance of the crispa parent. Floriferous but a little shorter than most viticella hybrids.

This lovely clematis is growing on a pergola in mostly mottled shade. It's flowers are delicate-looking 2-3" bells. Lot's of blooms! Blooms all summer. It likes E,S,W exposures. Prune C (cut all shoots hard to strong buds- 9-18" from ground)
