The American Clematis Society (ACS) greets potential visitors with an enticing display of clematis flowers, and invites them to enter the website. Once inside, you will discover that ACS was "founded in 1996 for the purpose of encouraging and promoting the development and improvement of clematis and to collect, record and share information concerning clematis." The website serves as a great informational resource, with brief descriptions for close to 300 varieties of clematis. The descriptions are accompanied by lovely images, and the site offers a periodically-updated collection of photos from ACS members as well. Site visitors will also find a Frequently Asked Questions section; information about membership; related links; and ordering information for a book dedicated to growing clematis in the United States.
