The Cape Cod Hydrangea Festival is an annual cape-wide celebration of the region's blue, pink, and white signature flowers and everything gardens on Cape Cod! This ten-day festival's main attractions are the daily tours of private gardens, each designed and maintained by the individual homeowners and carrying a unique charm. You are sure to enjoy such eclectic spaces, not to mention the good feeling of supporting a variety of local nonprofits which will benefit from the proceeds of each tour.
