Rutgers Gardens

Rutgers Gardens (20 ha / 50 acres) are horticultural, display, and botanical gardens, including arboretums, located on the Cook Campus, Rutgers University, 112 Ryders Lane, North Brunswick in Middlesex County, New Jersey, in the United States. The gardens are open daily without fee.

The gardens were first established in 1927, and are horticultural collections arranged in garden settings. Current collections include:
