This group consists mostly of vines and scrambling types of shrubs, together with a very few interesting hardy perennials. Banks and rocky slopes do not generally retain a considerable amount of moisture, and accordingly the material which is used should possess a vigorous constitution and low, spreading habit of growth, and the ability to withstand lack of moisture. The embankments which are composed of excellent heavy types of soil, and which are constantly cared for, may be covered with any of the low, spreading types of shrubs and perennials.

F. Small-flowering and Foliage Plants for Crevices Between Stepping-stones and for Paved Terrace Areas. This group consists of the very dwarf perennials and annuals which may be planted in the limited soil pockets between stepping-stones, between flagging on paved terraces, and in the narrow crevices between rock garden work. Most of the indigenous mosses which are adapted to either shady or sunny exposures can be readily transplanted to a corresponding condition, thus providing an appearance of age during the first year.
