The American Ivy Society is a not-for-profit organization dedicated to preserving the genus Hedera through education and promotion. AIS members are nurserymen, horticulturists, botanists and plant enthusiasts-professionals and non-professionals who share a passion for ivies of the world.
Goals of The American Ivy Society
Nomenclature: Develop a complete list of known ivy cultivars.
Clarify, simplify and reduce confusion over ivy names.
Some ivies have more than one name. Some names exist without a corresponding ivy. Descriptions and life-size photographs of old and new ivies in the Ivy Journal document and illustrate the cultivar with its correct name.
Register new ivy cultivars:
The International Registration Authority for Hedera was granted to the American Ivy Society in 1977. AIS has become not only the national authority on ivies and their nomenclature, but the international authority as well. AIS has members in 10 countries plus the US and Canada.
Because ivy lends itself well to many styles of topiary, the American Ivy Society has volunteered to become the official information source for topiary and topiary activities.
The Society maintains worldwide contact with gardeners and professionals who are looking for better ways to use and grow ivies. AIS amasses information and provides it to those who inquire.
AIS actively encourages new uses for ivy in the home and garden.
Cultivar and Hardiness Trials:
AIS is promoting hardiness testing of ivy both by cultivars and on a regional basis.
Greenhouse Production Trials:
AIS invites Commercial members to participate in testing new cultivars.
National Outdoor Hardiness Trials:
Institutions are invited to participate in successive evaluation programs to determine best cultivars for various sites, exposures and garden conditions. Individuals may also participate.
Write to AIS for further information.
AIS is establishing ivy collections in various parts of the country. AIS cannot be responsible for the accuracy of everyone's collection.
