The following rock plants may be used at the edges of pave ments or in areas where there is little or no traffic:

Outside the terrace wall or hedge, there must be another special planting. When the enclosure rises directly from the lawn, low plants similar to those of the foundation planting may be used, or greater stress be placed on low-growing flow ering shrubs, particularly laurel, azaleas in variety, andro meda, and cotoneasters. If there is a slope to take care of the change in grade, this can be included in the planting, espe cially if it is too steep for turf. Then the planting can be quite wide, but it should not be high, for shrubs shut out the view from the terrace and rob it of light and air. Low trailing shrubs, and low compact evergreens, and ground covers will blend the whole into the surrounding landscape. Matrimony vine, bittersweet, weeping forsythia, winter jasmine (if the location is quite protected), lespedeza, bluespirea (Caryop teris), and several of the larger cotoneasters look well in such a situation. In any case select for these places, plants that conform somewhat to the grade. Such plantings reduce the laborious task of mowing and maintaining grass on difficult slopes.

Foundation Plantings

Terrace plantings, though they belong to the more intimate areas of a property are allied to foundation plantings. In fact the evergreens and shrubs used in the front of the house can frequently be extended around the side or back, where they form a transition between house, terrace, or garden.
