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 planted small specimens last year. This year they are quite vigorous and carefree growers, topping their trellises now in early June. Also very floriferous, with a terrific May spectacle of large flowers in striking blue/lavender shades covering the plants. I expect additional blooms later in the season. Very pleased with 'Ramona.'

This clematis gives an outstanding display each May. It blooms sporadically thereafter all the way till winter. The seedheads are attractive year-round.

I planted this type of Clematis earlier this spring, and it's doing so well. It has climbed up my trellis aon on to my fence. It's blooming profusly now. Definately a good vine for zone 7.

I love the color of this clematis the most during it's first few days, then it tends to fade; still pretty, I just prefer the new blooms. Has grown very well. It is in full sun, maybe the blooms wouldn't fade as much in partial shade.
