In 1991, the gardens consisted of a sunken rose garden with fountain, stone-walled tulip garden, birch and spring bulb garden, fruit orchard, large vegetable garden, and raspberry row. A covered stone terrace extends along the south side of the residence. The property was purchased by Princeton University.
