Lonicera Caprifolium or Perfoliate Honeysuckle
The genus was named after the German physician Adam Lonitzer, author of several 16th-century botanical works. It comprises some 200 species found throughout the temperate regions of the northern hemisphere, which often cross-breed. Most are shrubs of upright habit, some are climbing species, and several are evergreen. This variability shows that honeysuckles can be used in all sorts of ways in parks and gardens.
Perfoliate honeysuckle is a stem-twining, climbing species from Europe and western Asia. It will climb up a support to a height of 5m (16 ft). The, 4 to 5cm (1½ to 2 in) long, are borne in whorls in the arils of the leaves which are fused and tightly clasped round the shoots. The blossoms are white, pinkish or yellowish and very fragrant, and appear in May and June. The leaves are greyish-green below, pruinose (covered with a whitish dust or bloom) at first but later smooth and bare.
Perfoliate honeysuckle is easily propagated by softwood cuttings as well as by cuttings of half-ripened and ripened wood and also by. It requires moderately moist and a sunny aspect. It is used to cover fences, walls, pergolas and trellises and is a hardy and attractive species, particularly when in flower.
Other frequently grown climbing species are Lonicera periclymenum, Lonicera henryii, Lonicera telemanniana, Lonicera brownii fuchsioides and Lonicera hectorii.
