Trees can make or mar the park. Too many kinds of them, or do not match, can rob garden of light and food soil and moisture, making it impossible to grow anything well. But a few well placed and the trees are well chosen to give parks differences and provide welcome summer shade. Big trees, like oak, elm, lime, poplar, beech, willow, cedar pine, and fir, only suitable for large garden, but there are sometimes narrow, straight-stemmed tree or large fastigiate form that can be grown in sufficient small garden. Examples are oak Dawyck Beech, fastigiate and fastigiate Tulip tree (lirioden-dron). The Lombardy Poplar is a fastigiate form of Black Poplar and its branches do not take up much space, but unfortunately his roots penetrate too far away to make it, both small, tree garden. Conifers, the spruce, cedar, juniper, fir, larch and pine are familiar For example, differs from other trees in a narrow, sometimes needle like leaf. Most, but not all, are green. Not much green tree, so that conifers do play a special little section in the garden, plus the fact that many of the cones in the habit contrasts with a more rounded shape broadleaf trees. Although naturally leafy greens, some conifers produce varieties with different leaf colors, usually blue-gray or gold. Most cone is allowed to branch from the ground surface but other trees are often planted on bare stems and is known as a standard.
