This is an elliptical flower garden, planted with mathematical precision. Maze-like walks and boxwood hedge borders add to the precise layout. In the center of the garden is a bronze sculpture of three satyrs holding a sundial. Ringing the formal garden are American Holly (Ilex opaca), White Pine (Pinus strobus), Norway Spruce (Picea abies ), Moss (Sawara) Cypress (Chamaecyparis pisifera), Ashleaf Maple (Acer negundo), Black Gum (Nyssa sylvatica), Japanese Apricot (Prunus mume), Common Horsechestnut (Aesculus hippocastanum), Sapphireberry (Symplocos paniclata) and White Ash (Fraxinus americana).

The formal garden offers an array of colors from May 15-October 1. The early-flowering peonies around the garden and irises around the central sundial are at their peak around Memorial Day.  Russian sage flowers around the sundial from June through September.  The 15 small flowerbeds among the boxwood hedges contain Dianthus, which is in bloom from May through September.
