Stop and Smell the Rhododendrons

The Rhododendron Festival is a beautiful Cape Cod event that highlights blooming flowers at the Heritage Museums & Gardens in Sandwich, Massachusetts. Every spring, as Cape Cod flowers are in full bloom, visitors enjoy guided demonstrations and learn about caring for rhododendrons. Comprehensive demonstrations cover ideal growing situations, watering, fertilizing, mulching, pest control, pruning, bud-pinching, and dead-heading to encourage optimal health and beauty.

Enjoy a Cape Cod Spring Tradition

The grounds at Heritage are a sight to behold with thousands of rhododendrons in bloom from late May into early June. Plan to spend a few hours or more here, exploring the acres of gardens, miles of walking trails, and the museums filled with art, American history, and antique autos. The kids will love riding on the carousel! 

Don’t worry about planning ahead. Advance registration isn’t required, and the programs are free with museum admission.
