The two acres of lovingly maintained gardens at Edgemont reflect one of its most prominent Jeffersonian qualities: the integration of the building into a well-planned landscape. As part of his restoration work, Milton Grigg designed the terraced gardens at Edgemont based on the outlines of old
beds and brick paths. Lined by rock walls and bisected by brick walkways, these grounds encompass formal parterres, a rose garden, a water garden, and a bowling green, among other features. At two corners are rubblestone outbuildings, one original and the other replicated by Grigg as a dovecote. The sum is a tranquil setting that provides abundant visual delights throughout the year.
