About Medfield Rhododendrons

Approach with care this fragile habitat of rare Rosebay rhododendrons with care — here you can experience one of very few populations of this important species.

What makes Medfield Rhododendrons a special place?
Medfield Rhododendrons is the site of an important and rare stand of Rhododendron maximum, the great laurel or rosebay rhododendron, one of only three species of evergreen rhododendrons native to eastern North America.

Rosebay rhododendrons are most abundant in the southern Appalachian Mountains, where they form extensive thickets. In New England they reach their northernmost range. At the turn of the 20th century, this plant became popular for its showy flowers, and overcollecting in the wild nearly wiped out the species. Only seven known populations exist today, including this one, the largest and easternmost population of rosebay rhododendrons in Massachusetts. Please help protect this fragile site.

A quarter-mile trail leads from the Woodbridge Road parking area to the stand of rhododendrons. Easy walking, although wet underfoot.

When to Visit
Year-round, daily, sunrise to sunset. Allow a minimum of 1 hour. Blooming for this species typically occurs in late June.

Conservation and Stewardship

Though listed today as a “threatened” species by the Massachusetts Natural Heritage and Endangered Species Program, rosebay rhododendrons were once more common in Massachusetts; approximately half of the historical populations in Massachusetts have been lost. At the turn of the 20th century, rosebay rhododendrons at this site in Medfield were approaching extinction due to overcollecting and cutting for their showy flowers.

The Trustees of Reservations acquired Medfield Rhododendrons to protect this important colony of rosebay rhododendrons. Currently, there are seven known populations, including this one. The Medfield Rhododendrons colony represents the largest and easternmost population in Massachusetts. Since large populations can better withstand changes to the environment, especially catastrophic events such as disease and flooding, this stand is likely to persist over time, thereby offering The Trustees of Reservations a vital conservation opportunity.

Please help us protect this important stand by respecting the fragility of the site. Surrounding the stand is wetland and river floodplain for the Stop River and Charles River basin.


Management Planning for Our Properties

Since 1891, The Trustees of Reservations have worked to protect special places in Massachusetts and maintain them to the highest standards. To ensure these standards are met, a program of careful planning and sound management is essential. Comprehensive property management plans are created for each reservation and are completely updated approximately every ten years. We often work with volunteers, property users, and members of the community to carry out this planning, which typically involves several steps:

  • Describing in detail the site’s natural, scenic, and historical resources; identifying management issues related to the protection of those resources. 

  • Describing how visitors use the property; outlining the opportunities that the property provides for people to become involved in the work of conservation and caring for their community.

  • Developing a detailed list of management recommendations, a work plan, and a description of financial needs for implementing the actions.

  • Developing a prescribed routine management program for the reservation that will guide staff work plans, volunteer involvement, and the allocation of human and financial resources.

Maps and Resources

Printed trail maps are distributed free from bulletin boards in parking areas. Please understand that supplies periodically run out. We recommend that you download a trail map before you visit.
