Edgerton Park is made up 22 acres of parkland. In 1965, it was turned over to the City of New Haven and several structures in the park in which Frederick Brewster built in the early 1900s have been preserved. The main house was destroyed but the original walls, greenhouses, the carriage house, the gatehouse and a bridge was preserved.

The property maintains an excellent greenhouse which is called the Crosby Conservatory. The state has continued to raise funds to restore and renovate park. The greenhouse is a very popular attraction as there are various plants from different parts of the world. There are also landscapes from the tropics. The tours offer hands-on demonstrations on gardening for groups and individuals visiting the park. The Carriage House is now used a horticultural library. Collections of books, periodicals and catalogs in gardening, flower arranging, and conservation is available in the library. The benches around the park have been donated by visitors and each of the benches has a plaque as a tribute to park users who have helped Edgerton Park develop.
