North Lawn (White House) requirement for public views of the White House. 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
Fagus sylvatica in the buds. In autumn, the tree builds the reserves that will sustain it into spring. Given good conditions, a bud can produce a shoot with up to ten or more leaves. The terminal bud emits a hormonal substance in the spring that halts the development of additional buds. This tendency, though very strong at the beginning of their existence, becomes weaker in older trees. It is only after the budding that root growth of the year begins. The first roots to appear are very thin (with a diameter of less than 0.5 mm). Later, after a wave of above
