CLEMATIS SPECIES

The description of species is a little more detailed than that for hybrids. They are much more diverse in shape and size and they come from different parts of the world. Species need little pruning and can be left to ramble at will through hedges, trees, etc., but where there are confined spaces such as on walls, then some pruning is sometimes necessary. The early-flowering varieties such as C. alpina, C. macropetala and C. montana need no pruning but can if necessary be cut back directly after flowering, which will be in May or early June, thus giving them plenty of time to grow during the summer. The later-flowering varieties can be cut back hard, treating them as Jackmaniis, but here again if space is no object they can be left to gracefully garland everything within their reach.

C. afoltata — ‘The rush-stemmed clematis’, so called because it looks exactly like a reed. The stems are slender with hardly any leaves which are extremely small. The flowers are produced at the leaf axil in groups of from two to six. They are small tubular-shaped, pale yellow, having a daphne scent, and are produced in profusion in April and May. A native of New Zealand it needs a warm wall in England and grows to a height of about 8-12 feet.

C. alpina — ‘The Alpine Virgin’s Bower’, Virgin’s Bower being the common name of clematis. Alpine gives its natural habitat, the Alps of Southern Europe. The flowers are satiny-blue, four-sepalled about 1-1 I^ inches wide with whitish petaloid stamens and hang downward like small bells, produced in March and April. Leaves are long, doubly ternate with coarse-toothed ovate leaflets. The flowers develop into attractive seedheads during the summer. The alpina varieties are actually atragenes, very closely allied to clematis and now

listed under clematis. They grow to a height of approximately 6-8 feet. The following are varieties of C. alpina:

C. alpina Columbine — Pale blue.

C. alpina Pamela Jackman — Rich, mid-blue.

C. alpina Ruby — Rosy-red.

Waxy-white flowers 1-2 inches in diameter, produced in clusters at the leaf axils in March and April. Grows to a height of 20 feet. Is quite hardy near the coasts, but inland needs the protection of a south or west wall.

C. armandii Apple Blossom — A pale pink variety.

C. calycina — ‘The fern-leaved clematis’ so called because its evergreen leaves are fern-like, dark green in the summer they turn to a bronzy hue in winter. The bell-shaped flowers, about 1 inch in diameter, are produced in profusion in mild spells from January to March. They are pale yellow in colour with red freckles on the inside. This variety does not always flower until it is well established, which is sometimes two or three years. Comes from the Balearic Islands and is sometimes called

C. balearica.

A member of the montana family, grows to a height of about 20 feet and produces masses of pale pink flowers about 2 inches in diameter in May and June. Will sometimes flower on the young wood during the summer.
