Columnar and pyramidal trees:
Oftentimes situations arise in the solution of landscape problems where the use of trees for their pyramidal or columnar habit of growth becomes almost a necessity. This necessity may arise because of such features being an important part of the landscape composition, or it may arise because of the screen effect which the designer is desirous of producing where trees must develop within a narrow space of from two to four feet. Most of the trees in this group develop normally into a pyramidal or columnar form like the pyramidal maples, the poplars, and the red cedar, quite unlike the spreading habit of the sugar maples, horse-chestnut, and beech. None of these trees lend themselves to use in plantations where a broad, informal character is desired in the picture; but all lend themselves for use in landscape planting where it is necessary to have a background of heavy foliage and an immediate garden planting close to these trees. The planter should always bear in mind that a background of trees of this type, planted closely together, will be very injurious to a flower garden development, provided the screen planting is located on the southerly side of the flower garden, thus throwing dense shade over the garden during the greater part of the day. From another point of view, however, this type of tree planted closely together will prove a wonderful asset if planted on the southerly side of some fountain or garden terminus where it is desired to produce a heavy shade.
