Plant Collections Network is a long-term collaboration between the American Public Gardens Association and the USDA–Agricultural Research Service. Formerly the North American Plant Collections Consortium (NAPCC), its first collections were accredited in 1996. The American Public Gardens Association Plant Collections Network coordinates a continent-wide approach to plant germplasm preservation, and promotes excellence in plant collections management.

Nationally Accredited Plant Collections make efficient use of available resources and strengthen collections through combined collaborative activities, such as:

  • Serve as a reference for plant identification and cultivar registration
  • Provide germplasm for taxonomic studies, evaluation, breeding, and other research
  • Compare holdings with other institutions to identify duplications and gaps
