Royal Horticultural Society.

Clematis. — Messrs Jackman, of Woking, staged about thirty plants of their new hybrid Clematises, which we admire the more, the more we see of them, so deserving are they of general culture, either in pots or planted out.  Among those staged on this occasion, we noted the following as distinct and good: C. Baroness Burdett Coutts, a large-flowered variety, of a delicate rosy lilac; Lady Stratford de Ratcliffe, a beautiful lavender-blue, large and fine; the Queen, a delicate lilac; and Vesta, an eight or ten-petalled flower, of remarkably good form and pearly whiteness, with purple stamens.  The majority of the plants were 18 inches to 2 feet high, and as much in diameter, bearing from thirty to sixty flowers each.

Spring-Flowering Clematises.
At a meeting of the Royal Horticultural Society, on April 16, a group of new spring-blooming Clematises was staged by Messrs. Jackman, of Woking. There were seven finely grown and flowered plants, trained over oval wire frames, that were studded with large eight-petalled flowers of varying tints. Of these, four were deemed worthy of first-class certificates, viz: Fair Rosamond, silken white, tinted on the edges with pale soft mauve, and having purple stamens, flowers large in size, stout, well formed, and distinct; Stella, pale violet, paling off to lilac on the edges of the petals, and with a flame of pale puce along each, flowers large and of fine quality; The Queen, very pale mauve, with a slight pale green flame along each segment, large and very fine; and Vesta, pure white, with a fine primrose-green stripe along each petal, a beautiful white Clematis. The others were scarcely less inferior in size and beauty, and comprised Lady Stratford de Redcliffe, pale shining mauve, with a creamy flame along each petal, flowers of fine form, and vigorous habit. This variety will in all probability prove the precursor of a new race, as it has resulted from a cross between the spring-flowering C. Standishii and the summer-flowering C. Jackmanii, the principal change being in the habit, which is much freer and denser in growth than is usually seen in this section. There were also Maiden's Blush, pure white, with a flame of primrose-green on each segment, dark stamens, very fine; and Lord Derby, pale silken mauve, with a dash of cream along the centre of the petals, very delicate and fine. These will form valuable additions to this beautiful class of spring-blooming plants, many of which could be bloomed in the open air if planted in warm, sheltered, and sunny spots, and in large domains.

New Sweet-scented Large-flowered Clematis. [by Thomas Moore]
...This fine group of new scented varieties has been bred between C. Standishii, C. Fortunei, and some of the best forms of C. patens, by Messrs. George Jackman and Son, of Woking, and we have had the pleasure of leisurely inspecting and noting their qualities during the present season [...] The following are the new varieties in question:
C. Vesta; a pure white, having the sepals marked by a cream-coloured bar, very beautiful; also primrose-scented.
