Plant Collections Network – Collaborating Since 1995

American Public Gardens Association has partnered with USDA Agricultural Research Service (ARS) since 1995 to develop Plant Collections Network.

We work closely with staff at US National Arboretum to accredit exceptional plant collections in public gardens, train peer site reviewers, and promote standards of excellence in plant collections management. Together with curators within the National Plant Germplasm System, we build and safeguard comprehensive collections of economically important plants for research, conservation, and public education.

Collecting and Curating the Kentucky coffeetree, Gymnocladus dioicus

Collaboration of the authors over the past ten years has resulted in the acquisition and preservation of one of the most comprehensive ex situ woody plant seed collections represented in the U.S. National Plant Germplasm System and a Nationally Accredited Gymnocladus dioicus living collection at the Brenton Arboretum. Systematical site selection and population sampling techniques strived to ensure a collection adaptable to a wide-range of climatic factors. The firsthand knowledge of these genetic resources will help with species management efforts and demonstrate the importance of gene banks and arboreta in the conservation of tree genetics.
