Master Gardener Tours
Save the dates for the 2027 Cape Cod Hydrangea Festival: July 9 through 18!
Every summer the Master Gardener Association of Cape Cod participates in the Cape Cod Hydrangea Festival, a celebration of the region's signature flowers and everything "gardens" on Cape Cod. In addition to offering a variety of Master Gardeners' private gardens to tour, we offer daily garden talks or demonstrations in a number of our gardens.
Hydrangea Festival garden tours are $5 cash per person per garden, payable at each garden at time of entry. No reservations needed! Gardens are open from 10am to 4pm and only on the days specified in the Hydrangea Festival Guide. All tours are rain or shine, and non-refundable.
Proceeds from the Master Gardener Association garden tours benefit scholarships for Barnstable County students pursuing degrees in horticulture or agriculture, as well as our Cape-wide community outreach programs.

Pollinator Pathways on Cape Cod
All seven of our 2026 display gardens included native flowering perennials, as well as shrubs, trees or grasses. Pollinator Pathways members participated in selected gardens to share the importance of gardening for habitat to support our local pollinators, including bees, butterflies, hummingbirds, and other pollinating insects and wildlife. Learn how you can be part of the Pollinator Pathway movement on Cape Cod at link above.
