Trachelospermum (Greek, neck and seed, referring to the fact that the seed has a neck). Syn., Rhynchospermum. Apocynaceae. Glabrous or slightly tomentose-puberulent shrubs, the typical species tall-climbing, grown in the warmhouse and a favorite out-of-doors in the South.
Leaves opposite, distantly feather-veined: cymes lax, terminal or pseudo-axillary: fls. white; calyx small, 5-parted, with 5-10 scales or glands inside at the base; corolla salver-shaped, tube cylindrical, 5-lobed, lobes oblong, twisted to the left, overlapping to the right; disk annulate, truncate or 5-lobed; ovary 2-carpelled: follicles elongate, slender, terete. — About 16 species, E. Asia and Malaya.
Trachelospermum is a most satisfactory greenhouse shrub for a general collection. It requires no special treatment, except that the plants should be kept on the dry side during the winter. It requires several years to work up a good-sized specimen. Young plants should be given warmhouse treatment and encouraged to grow. Large well-established specimens thrive in a coolhouse. In summer the pots may be plunged outdoors in a partially shaded position. The species is propagated by cuttings of half-ripened wood taken with a heel in spring. The star jasmine is one of the many good old standard greenhouse plants that are too little seen nowadays. The specimens require considerable room, and the gardener is sometimes compelled to keep them in a cold pit until the chrysanthemum season is over, although this treatment is not to be advised. It is a tender evergreen shrubby climber from China, with fragrant white five-lobed flowers. It is a favorite in the South, where it, is grown out-of-doors and known as the "confederate jessamine." In northern conservatories it is generally known under its synonym, Rhynchospermum. Handsome specimens may be grown in large tubs, making dense bushes 3 to 4 feet high and as much in diameter.
T. divaricatum, Kanitz (T. crocostomum, Stapf). Similar to T. jasminoides in habit, but differs in having slightly smaller buff or pale orange-colored fls. with exserted stamens, pointed in bud, and smaller lvs. Japan, Korea. G.W. 12, p. 415.—It is more hardy than T. jasminoides.
