The Princeton Nurseries site is significant for its association and contribution to the history of commercial horticulture in the United States. Princeton Nurseries was once the largest commercial nursery in the United States. At its peak it occupied 1,000 acres and employed 300 people. The nursery was established in 1913 by William Flemer, Sr. but relocated in 1995 to Allentown, New Jersey. Over 214 acres of the former nursery are in the public domain, owned either by South Brunswick Township or the State of New Jersey.

The heart of the nursery contains the former sales and administration building, a former blacksmith shop, two large cold storage buildings, a propagation house, and several greenhouses. Additionally, the district contains former farm fields, numerous horticultural areas, former worker’s housing, and former Flemer family dwellings. The former sales and administration building along with the former blacksmith shop currently serve as the headquarters and education building for the Delaware and Raritan Canal State Park and is in good condition. Other buildings throughout the nursery range from poor to good condition. Many of the landscape features are becoming overgrown and compromised by invasive vegetation. 

The grant will help fund the preparation of a cultural landscape report that will guide restoration of the site.
