More popular even than the Jasmine as a fragrant climber is the Honeysuckle, the twining branches of which will bind themselves round a fence, over a tree stump, among the "lattices" of trelliswork, and round pillars. The common Honeysuckle is known to botanists by the somewhat formidable name of Lonicera Periclymenum; there are several garden forms of it, such as Early Cream, Early Dutch and Late Dutch. Flava is the yellow trumpet Honeysuckle. Flexuosa and brachypoda, with pale very fragrant flowers, are the same species, and the gold-netted (aurea reticulata) is a garden form of it. Sempervirens is the scarlet trumpet Honeysuckle. There are two winter-blooming species with white flowers, fragrantissima and Standishii. The Honeysuckles will grow in almost any soil if the site is not very hot and dry. The only pruning which they need is thinning when crowded.
Kerria japonica, double form, is good for a north wall.
The Magnolias give us some of our noblest shrubs and trees, and the large-leaved grandiflora is generally grown on a wall. Those who think of planting this fine evergreen should endeavour to get the Exmouth variety, which is finer than the common. Ferruginea is another form of it. They should not be planted on a cold aspect; a south or west wall is desirable. Magnolias conspicua, Lennei, Soulangeana and stellata (syn. Halliana) are beautiful deciduous Magnolias that may be planted in shrub beds and borders.

The Myrtles have a body of faithful admirers, who love the plant for its perfume. One could hardly deal with it appropriately among climbing shrubs, but for the fact that it is often planted against walls for the sake of shelter; it does not grow up the wall like a climber, but gains vigour from the protection which it receives. Even with the wall-shelter, provision should be made for protecting the plant in severe weather. The common Myrtle is Myrtus communis, and there are several varities of it, including a narrow-leaved, (angustifolia) and a variegated.
The Passion Flower (Passiflora caerulea) is one of those plants which tantalize their admirers by just falling short of that perfect hardiness which enables one to plant them anywhere without fear, but they will live in the open in sheltered places, and after all, the plant is so interesting and beautiful that it is worth a risk. The white form, Constance Elliott, may also be planted. These Passion flowers will serve to give diversity to the furniture of a long pergola, and variety adds interest and charm.

Periploca graeca may be planted to vary the interest of a collection of climbers. Although it is not showy, its greenish purple flowers are quaint. It will do for the pergola.
Polygonums comprise a large number of species, but few are suitable for climbing, and the best by far is Baldschuanicum, which grows very fast and twines its stems round any object. The white flowers are produced in panicles from early summer to September, and it is often at its best, a fleecy cloud of bloom, in early autumn. The plant is hardy, and it grows so fast and blooms so profusely that it is a splendid subject for covering arbours, arches and pillars. It may also be used for the pergola.
Roses must, of course, be included in any collection of climbing shrubs. They are the most beautiful of all plants for covering arches, arbours, pillars, pergolas, fences, walls and banks. It may here be explained that in passing references to Rose-pruning in the present chapter, the pruning of dwarf and standard Roses of the Hybrid Perpetual, Tea and Hybrid Tea classes, which bloom on the current year's wood, was referred to. The best of the climbing Roses belong to the multiflora, polyantha and Wichuraiana sections, and these flower best on long canes made the previous year, so that they come within the ranks of the majority of flowering shrubs in respect to pruning. In brief, they do best when the flowered wood of any particular year is pruned out after blooming, giving room to the young canes which spring up from the base. As with many shrubs, it is sometimes desirable to retain the lower part of an old rod for the sake of a strong young cane which is growing on it, and which is better placed, or more vigorous, than canes from the rootstock.
It would not be possible to deal fully with the pruning, general culture and varieties of so important a shrub as the Rose in a general work. These matters are dealt with, alike as regards climbing and dwarf Roses, in the sister volume, "Roses and Rose Gardens." It is desirable, however, to point out the beauty and value of what are called climbing Roses in connection with the subject of the present chapter. The varieties are constantly changing, new coming into the catalogues and old dropping out every year; but there are certain sorts of such outstanding merit, that it is difficult to improve on them, and they are likely to stand for many years. Such are the beautiful Wichuraianas Dorothy Dennison, Excelsa, Jersey Beauty (for banks), Dorothy Perkins, Lady Gay, Alberic Barbier, Lady Godiva, and White Dorothy; Crimson Rambler and Blush Rambler, Carmine Pillar, American Pillar and Shower of Gold. All these have the elements of long-continued favour. All are good for pillars, arbours, arches and pergolas. All the Wichuraianas are good for banks, Jersey Beauty and Alberic Barbier particularly so. In mild winters they are evergreen. If the varieties as a whole are weak, it is as wall plants. None of the Wichuraianas and Ramblers are quite at home on a wall. For this purpose the planter should choose Madame Alfred Carrière. For a lofty wall, especially with a cold aspect, there is probably nothing better than William Allen Richardson. For low walls
