Neutral	Joan	On May 17, 2009, Joan from Belfield, ND (Zone 4a) wrote: Editor's Note 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.
Positive	Shirley1md	On Apr 1, 2006, Shirley1md from Ellicott City, MD (Zone 7a) wrote: This Clematis has three colors to its flowers. Early blossoms have a reddish center surrounded by fuchsia and then a violet color toward the edge of each tepal. Creamy colored stamen complete this wonderful repeat bloomer.
