When it is desired to have as many plantings as possible around a patio or terrace, a space for growing plants must be left between the floor and the side wall of the house. Twelve inches provides for vines, two or more feet are necessary for shrubs. Or, a substitute arrangement can be made for tubs or plant boxes. When the structure is not enclosed on any side by a house wing, a low hedge or loose flowering shrubs on one or two sides, give a feeling of enclosure. A spacious terrace calls for a spacious planting. If the floor is entirely of flagstones or other paving, the greater part should be in shade through the hottest part of the day. A three-foot minimum space must be left between the floor and side wall of the house for a heavy planting. Where possible use evergreens. Rhododendron, azaleas and other broadleafed evergreens are used where these are grown. Dwarf conifers, or other soft leafed plants are suitable in other regions.
Select plants which are entirely free from pests to avoid the problem of spraying. Many small terraces lend themselves to annuals, perennials and the like throughout the spring and summer. This is the most economical kind of planting. Carried out with taste, a colorful and charming picture can result. (See Flower Gardens.)
