frigidus, C. henryanus and C. salicifolius. The name C. xwatereri is loosely used to cover this group but there are some outstanding named cultivars which are free-fruiting and semi-evergreen in nature. Of these two of the best with red fruits are 'Cornubia' and 'St Monica', while 'Exburyensis' and 'Rothschil-dianus' have yellow fruits, those of the former becoming pink-tinged with age. A single specimen of any one of these cotoneasters will make a bold feature in a lawn or border. Among those of medium size are the grey-leaved C. franchetii var. sternianus and the small-leaved, mound-forming C. conspicuus, both of which are evergreen and free-fruiting. Two of the best cotoneasters are C. splendens and C. bullatus var. floribundus. The first of these rarely exceeds 6ft(2m) and has small, neat leaves and a wealth of bright orange fruits, while the latter will reach loftijm) and bears clusters of bright red fruits against handsome, conspicuously veined leaves. Walls of houses and out-buildings, as well as fences and trellises within the I garden (or on the boundary) provide us with accommodation for an 1 interesting range of plants-climbers, both shrubby and herbaceous, together with many of the more spectacular flowering shrubs of borderline hardiness, such as abutilons, the evergreen ceanothus and myrtles which, if grown away from the shelter and extra warmth of a wall, would not survive or would suffer considerable winter damage in colder districts. Indeed, house walls and porches in particular, as well as low walls or balustrading which makes divisions within the garden, provide an opportunity to grow many exotic, exciting and unusual plants (see select lists on pp. 85 to 89). Tree stumps, posts, tripods and pergolas can all provide a home for well-chosen climbing plants, such as akebia, clematis, honeysuckles or climbers of like character. There are a number of vigorous vines and roses as well as such familiar and lusty climbers as wisteria and Russian vine, Polygonum baldschuanicum, which will festoon decrepit trees. Some are equally appropriate for smothering an unsightly building or garden shed or, trained on trellis, to screen an eyesore, such as a domestic oil-storage tank. Difficult, unmowable banks may be rapidly and attractively clothed in a labour-saving manner with rambler roses or suitable climbers. These include such larger-leaved ivies as Hedera colchica and H. canariensis and their cultivars, and such honeysuckles as Lonicera etrusca and L. japonica. Less vigorous climbers, such as cultivars of Clematis texensis and Tro-paeolum speciosum can contribute welcome colour and variation of flower and leaf when trailing over heathers or non-flowering hedges. The uses of climbers and wall shrubs within the garden are indeed many and varied; it is, however, necessary to consider their individual requirements in order to choose the right plant for the right wall or other specialized position.
