JASMINE

P. Hardy or tender climbers and shrubs which succeed on most soils, given sun and good drainage. Jasminum officinale is the old-fashioned jasmine which bears white, very fragrant flowers from June to September on slender semi-evergreen shoots. It is a self-supporting, hardy climber and will reach 40 ft. high if grown against a wall. J. nudiflorum is equally hardy, bearing bright yellow flowers on the leafless branches during mild weather from November to February. It tolerates some shade and is happy even on a north wall. On a wall it will reach 10 ft. but can be kept to half this height by pruning. May also be grown on a trellis, pergola or fence where it flowers later and rather less freely. Correct pruning is important — cut back hard all shoots which have flowered and do this immediately after flowering. J. stephanense bears fragrant, pale pink flowers in June and July, followed by glossy, black fruits. It is deciduous. Among the less hardy kinds, J. polyanthum, the deciduous climber, is hardy only in milder districts in the south and west and must be grown in a cool greenhouse elsewhere. The very fragrant white or blush flowers are suffused with rose and appear as early as January under glass. J. grandifiorum is another fragrant white species which flowers during summer and autumn in a warm greenhouse. It is semi-evergreen. J. primulinum is bright yellow, evergreen and flowers in winter in a cool greenhouse. It succeeds against a warm wall in mild localities where it may reach 20 ft. but requires protection in very severe winters. J. parkeri is an attractive, though little known, rock garden shrub. It makes an evergreen bush only 8—12 in. high, which bears solitary yellow flowers in June. It is both fragrant and hardy. Most jasmines ‘strike’ readily from summer cuttings taken in a warm frame.
