The Olmsted plan presented the landscape largely as seen today: retaining or planting large specimen trees and shrubs on the perimeter to create boundaries for visual privacy, but opened with generous sight lines of the house from north and south. The lawn is planted with a grass variety called tall fescue ("Festuca arundinacea)." Trees on the North lawn include fern-leaf beech ("Fagus sylvatica asplenifolia"), American elm ("Ulmus americana"), white oak ("Quercus alba"), white saucer magnolia ("Magnolia × soulangeana"), red maple ("Acer rubrum"), American Chestnut Tree ("Castanea dentata)" and American and English boxwood

They are often dioecious so a male and female tree in proximity is required to set seed, however, many trees are also polygamo-dioecious, which means they have both male and female flowers on the same tree. The fruit is a black-blue, ovoid stone fruit, about 10 mm long with a thin, oily, bitter-to-sour tasting flesh and very popular with small bird species. There are from one to three fruits together on a long slender stalk. They are a valuable energy food for birds, especially the American robin. "Nyssa sylvatica" forms
