Landscape gardening has often been likened to the painting of a picture. Your art-work teacher has doubtless told you that a good picture should have a point of chief interest, and the rest of the points simply go to make more beautiful the central idea, or to form a fine setting for it. So in landscape gardening there must be in the gardener's mind a picture of what he desires the whole to be when he completes his work.
From this study we shall be able to work out a little theory of landscape gardening.
Let us go to the lawn. A good extent of open lawn space is always beautiful. It is restful. It adds a feeling of space to even small grounds. So we might generalize and say that it is well to keep open lawn spaces. If one covers his lawn space with many trees, with little flower beds here and there, the general effect is choppy and fussy. It is a bit like an over-dressed person. One's grounds lose all individuality thus treated. A single tree or a small group is not a bad arrangement on the lawn. Do not centre the tree or trees. Let them drop a bit into the background. Make a pleasing side feature of them. In choosing trees one must keep in mind a number of things. You should not choose an overpowering tree; the tree should be one of good shape, with something interesting about its bark, leaves, flowers or fruit. While the poplar is a rapid grower, it sheds its leaves early and so is left standing, bare and ugly, before the fall is old. Mind you, there are places where a row or double row of Lombardy poplars is very effective. But I think you'll agree with me that one lone poplar is not. The catalpa is quite lovely by itself. Its leaves are broad, its flowers attractive, the seed pods which cling to the tree until away into the winter, add a bit of picture squeness. The bright berries of the ash, the brilliant foliage of the sugar maple, the blossoms of the tulip tree, the bark of the white birch, and the leaves of the copper beech all these are beauty points to consider.
