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
Luzula sylvatica grow on acidic soils in damp habitats. "L. sylvatica" can be found on stream banks and well-drained, open woodland, as well as in open ground and rock ledges and peaty heath moors. Despite its preference for acidic soils, it can tolerate most soil pH levels. The leaves of "Luzula sylvatica" are picked in winter by golden eagles to line their eyries. The flowers and seeds of "L. sylvatica" are also the sole food source for the larvae of the "Coleophora sylvaticella" moth. "Luzula sylvatica" is commonly used in horticulture — its thick, patch-forming habit (which allows the plant to act
