Heritage Museums and Gardens
Heritage Museums and Gardens (100 acres), formerly the Heritage Plantation of Sandwich, is located at 67 Grove Street, Sandwich, Massachusetts. The public garden, with its nationally significant collection of rhododendrons hybridized by Charles Dexter, over 1,000 varieties of daylilies and extensive hosta collection, is complemented by three gallery buildings containing a world-class collection of American automobiles, American folk art and a working 1919 carousel and rare carousel figures. Heritage is open April - October 7 days a week, and on weekend evenings between Thanksgiving and Christmas for its annual Gardens Aglow festival.
The museum's grounds were once the estate of noted rhododendron hybridizer Charles O. Dexter, where between 1921-1943 Dexter developed between 5,000 and 10,000 seedlings annually. He planted many on the site. In 1969, Josiah K. Lilly III (1916–1995) and his wife established Heritage Plantation of Sandwich on the property.
The gardens and grounds
The gardens' principal interest is its collection of thousands of rhododendrons, which now include 125 of the known 145 Dexter cultivars. Their typical bloom time is from Memorial Day Weekend to mid-June. This collection has been painstakingly recovered since 1972, as Dexter's own named cultivars had been scattered without records. Each cultivar had to be recollected from gardens and nurseries up and down the East Coast. The site was prepared in 1972, and by the summer of 1977 it included over 300 plants representing nearly 100 cultivars, with an additional 25 cultivars as small plants in the nursery. All are now mature plantings.
The ground also include the Old East Mill, a windmill built in Orleans, Massachusetts in 1800, and extensively restored in 1999-2000. Visitors may view its interior on special days. In 2002 a labyrinth was also added to the grounds, designed by Marty Cain, one of the best-known labyrinth designers in North America. Also located on the grounds is the Hart Family Maze Garden established in 2005. A Cape Cod Hydrangea garden was added in the fall of 2008. For children and families, Hidden Hollow was added in 2010. It is a Certified Outdoor Nature Classroom where children and families can rediscover the joy of being outside together.
