Trachelospermum jasminoides (common name: star jasmine)
Propagation: Seed - we have no information for this species but suggest sowing the seed in a greenhouse in early spring. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Cuttings of half-ripe wood, 6 - 8cm with a heel, August in a frame. Ensure that the milky sap, which is excreted from the heel when the cutting is taken, has dried out before the cutting is inserted in the soil. Fair to good percentage[1].
Layering in summer[2]. The plant self-layers, sending out roots from leaf nodes and stem tips wherever they touch the ground[3].
Cultivation: Requires a well-drained moderately retentive soil in full sun or with part-day shade[4]. Requires a good humus-rich soil[5]. Succeeds in moderately acid or alkaline soils[6]. Requires the protection of a wall[5].
Plants are not very hardy outside the milder areas of Britain, tolerating temperatures down to about -5°c when grown against a wall[4]. They tolerate temperatures down to about -10°c according to other reports[6][7]. Plants are slow-growing when they are young and they are then more susceptible to damage by frost and cold winds[5][6]. They may put on no new growth for the first 2 - 3 years after planting out[6].
A twining plant[8]. Plants are self-clinging on walls according to other reports[9][4].
Flowers are produced on short laterals that grow from old wood[4]. The flowers are deliciously scented[3].
Range: E. Asia - China, Japan, Korea.
Habitat: Found as a weed in Chinese gardens where it grows on walls and trees[10].
Medicinal: The leaf is restorative and tonic[11][12]. This plant is especially useful for the aged[11].
The flowering stem is analgesic, antibacterial, antirheumatic, antispasmodic, depurative, emmenagogue, febrifuge, resolvent, tonic and vasodilator[13][12]. A decoction is used in the treatment of rheumatoid arthritis, sore throats and various boils and abscesses[10][13].
The seed is cardiotonic and haemostatic[12].
The whole plant is cooked with other foods and used to treat rheumatism[12].
Soil: Can grow in light, medium, and heavy soils.
In Leaf: Evergreen
Flower Type: Hermaphrodite
Also Known As: Rhynchospermum jasminoides.
