An arboretum is a facility dedicated to the cultivation of woody plants for public display and both scientific and educational purposes, because the Frelinghuysen Arboretum is a place of learning, each garden teaches a lesson.

An arboretum is also a museum with a living collection. The following describes some of the lessons and collection components. For additional details, please refer to interpretive signage located throughout the gardens.

The Frelinghuysen Arboretum was once the country home of George Griswold Frelinghuysen and his wife, Sara Ballantine Frelinghuysen, and was called Whippany Farm. The Frelinghuysens commissioned the Boston architectural firm of Rotch & Tilden to construct a summer home and carriage house on the property. The mansion, a fine example of Colonial Revival architecture, was built in 1891 and the property was designed in the style of an English country estate. The mansion features Federal urns, swages, and Ionic columns. A Palladian window overlooks the Rose Garden. The estate was planted with trees and shrubs considered essential to an English-style landscape. The home, large trees, and Great Lawn evoke the feeling of the Country Place era.

The Frelinghuysens spent 40 summers at Whippany Farm in fashionable Morristown.  Their daughter, Matilda E. Frelinghuysen, inherited the 127-acre property from her parents and participated in plans to convert it into a public arboretum in memory of her parents. Whippany Farm was bequeathed to Morris County in 1969, and was entered on the State and National Register of Historic Places on September 22, 1977.  The Frelinghuysen Arboretum was dedicated in 1971.
