Plant Collections Network
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 may serve as references for plant identification and cultivar registration. Collection holders make germplasm available for taxonomic studies, evaluation, breeding, and other research. Participating institutions compare holdings with others to identify duplications and gaps. This makes efficient use of available resources, strengthening collections through combined collaborative activities. Click here for an introduction to the program.
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.
