Hydrangea University 2025

Heritage Museums & Gardens and the Cape Cod Hydrangea Society are pleased to continue our partnership to present the ninth annual Hydrangea University – the premier event of the annual Cape Cod Hydrangea Festival. During this symposium-style event, expert guest speakers will inspire and entertain while increasing participants’ knowledge of hydrangeas.

After the program, participants will have the opportunity to tour the Cape Cod Hydrangea Society Display Garden and the North American Hydrangea Test Garden. Admission to all of Heritage Museums & Gardens will be included with registration. Advance registration is required, and we expect this popular program to sell out quickly.

Location: Check in at the J.K. Lilly III Automobile Gallery
