Cultivar Registration

Cultivar Registration of Unassigned Woody Ornamentals

The registration of woody ornamental cultivars for those groups that do not have an appointed International Cultivar Registration Authority (ICRA) began in 1948 under the auspices of the American Association of Nurserymen (AAN). The Arnold Arboretum served as the International Registration Authority for Unassigned Woody Ornamentals between 1959 and 1980. In 1980 the American Association of Botanical Gardens and Arboreta (AABGA) assumed responsibility for coordinating the registration of unassigned woody ornamentals within the United States and Canada. Since this date the U.S. National Arboretum (1981-1984), Longwood Gardens (1984-1993), The Royal Botanic Gardens, Ontario (1993), and Brooklyn Botanic Garden (1994-present) have served as the IRA for Unassigned Woody Ornamentals.

A directory of ICRAs and registration guidelines available here.
