The Morton Register of Arboreta is a comprehensive list and database of named arboreta and other public gardens that have a substantial focus on woody plants. ArbNet offers an Arboretum Accreditation Program that provides standards for the establishment and development of an official or bona fide arboretum. The Morton Register of Arboreta and the Arboretum Accreditation Program are available through ArbNet, an online, interactive community of arboreta that supports the common interests of tree-focused public gardens. ArbNet is sponsored and coordinated by The Morton Arboretum, in cooperation with the American Public Gardens Association.

How do I get official Arboretum status?

While the Association cannot directly assist or fund aspiring public gardens, our member Longwood Gardens’ Fellows Program put together this Guide and Toolkit to help.
