Question: I am looking for names of white species of clemtis and where to find them.
Answer: The two most famous (and beautiful in my opinion) white varieties of clematis are "Henryi" and "Duchess of Edinburgh". Both are available from White Flower Farms at 1-800-503-9624 or http://www.whiteflowerfarm.com
