Nomenclature Committee


The American Hosta Society is dedicated to the study of the genus Hosta. Part of the many benefits provided for members and the hosta nursery trade is the Society’s involvement in maintaining standards for the classification and nomenclature of Hosta species and cultivars. The society has made this task part of its mission by maintaining a classification and nomenclature committee and by supporting the registration of Hosta cultivars.

The mission of the nomenclature committee is to prevent confusion over species and cultivar names in the gardening world and establish standards by which hostas are named. In botany and horticulture, the naming of plant species follow the rules of the International Code of Nomenclature for algae, fungi, and plants. The rules for naming garden plants (cultivars), are set forth in the International Code of Nomenclature for Cultivated Plants (ICNCP), published by the International Society for Horticultural Science (ISHS).

Cultivar names are registered by the International Registrar Genus Hosta under the auspices of the American Hosta Society. More information is available on the Hosta Registry website at Registration provides benefit to registrants by establishing a record of “ownership” of a cultivar (and its name), and provides the means for having cultivar names and their description published per ICNCP rules.
