Some resources list all parts of all Clematis species poisonous if ingested. The toxic principal is Anemonin, and symptoms after ingestion include intense burning sensation in the mouth and mouth ulcers.
Dermatitis and skin irritation has also been recorded, as have allergies and hay fever type symptoms from pollen inhalation.
We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to caution gardeners, parents and pet owners to look further for more information.

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.
