The Hydrangea collection at Norfolk Botancal Garden is designated an Official Plant Collections Network. Plant Collections Network is a program of the American Public Gardens Association in cooperation with the USDA Agricultural Research Service. As part of this national designation, the Garden is committed to holding and developing a collection of documented living plants according to specified standards. In addition, Plant Collections Network-recognized plant collections are available for selection and breeding, taxonomic study evaluation, utilization, and other research purposes.
Hydrangeas are planted throughout Norfolk Botanical Garden, but most are concentrated in the 1.5 acre Kaufman Hydrangea Garden, which features approximately 300 hydrangeas representing 20 different species and 200 different cultivars.
