Given lime-free soil, one of the many camellias can be trained as a wall shrub, either against a north-facing wall or a west-facing one. In such situations they are less likely to suffer from summer drought (which causes bud drop) or to have their flowers damaged by early morning spring sunshine following frost. By reason of their winter or very early spring flowers, and in certain cases their habit of growth, some are particularly appropriate for wall cultivation. A choice might be made from the very free-flowering 'Inspiration' (C. reticulata x С. saluenensis) with large, semi-double, deep pink blooms; C. japonica 'Nobilissima', paeony-form, white and very early flowering; C. japonica 'Sylva' rose-red; and 'Leonard Messel' (C. reticulata x С. x williamsii 'Mary Christian') a remarkably hardy cultivar with large, semi-double, coral-pink flowers. One of the most worthy of space is C. sasanaua 'Narumi-gata', perhaps the only cultivar of this beautiful winter-flowering species that performs reliably in the British Isles. It produces its large pink-tinted white flowers with reasonable regularity on established plants. Members of the С. x williamsii (C. japonica x C. saluenensis) group of hardy hybrids are also very adaptable to wall cultivation, flowering freely and reliably from November to May. 'Donation' produces quantities of very large semi-double, beautifully veined pink flowers and is reliable and spectacular if now somewhat over planted. 'E.G. Waterhouse' is of more recent introduction and has formal double, pale pink flowers, while 'J.C. Williams', compact in habit and free-flowering, bears single, rose-pink flowers. This last is often considered the finest of all camellias. 'November Pink' is very early coming into flower and continues intermittently throughout winter and spring, as the weather allows.charming and (often) spectacular hardy plants that can be grown in gardens I-hence their singling out for special mention. They are remarkably adaptable and will adorn all types of walls, fences, pergolas, trellis and tripods; they will also scramble through trees, climb among roses or over I hedges and through plantings of heathers or even weave their way among boulders. To give of their best against a wall or fence, the large-flowered garden clematis need to be planted in a sunny site where the root area will be shaded by dwarf shrubs or other plants. For the best results a well-cultivated and well-drained, rich, loamy soil is desirable. They are excellent for growing on chalk or limestone and respond to generous annual feeding; thorough watering may be necessary, particularly at times of drought. The species are particularly successful when festooning pergolas or wooden tripods. Among the most reliable and desirable of these in general cultivation are Clematis alpina which bears solitary, powder-blue nodding flowers in April and May. This is a charming dwarf to scramble over a low wall or boulder. C. alpina 'Frances Rivis' (syn.
