Our research programs
The North American Hydrangea Test Garden grows plants from plant hybridizers and nurseries for evaluation in the climate of Cape Cod. New introductions are added annually and new evaluations will be added as the plants and their performance are assessed. As the gardens expand, Heritage will be presenting horticulture research to our visitors as well as the horticulture community.
