Rhynchospermum jasminoides Lindl.
Trachelospermum jasminoides is a species of flowering plant in the family Apocynaceae, native to eastern and southeastern Asia (Japan, Korea, southern China and Vietnam). Common names include Star jasmine, Confederate jasmine, Chinese jasmine, Chinese ivy and Trader's compass.
Trachelospermum jasminoides is an evergreen woody liana growing to 10 feet (3.0 m) high. The leaves are opposite, oval to lanceolate, 2–10 cm long and 1-4.5 cm broad, with an entire margin and an acuminate apex.
The fragrant flowers are white, 1–2 cm diameter, with a tube-like corolla opening out into five petal-like lobes. The fruit is a slender follicle 10–25 cm long and 3–10 mm broad, containing numerous seeds.
A valuable perfume oil is extracted from the steam distilled or tinctured flowers and used in high end perfumery. In a dilute form, tinctured flowers are much used in Chinese, Vietnamese and Thai incenses. A bast fibre is produced from the stems.
Trachelospermum jasminoides is commonly grown as an ornamental plant and houseplant. In gardens, public landscapes, and parks it is used as a climbing vine, a groundcover, and a fragrant potted plant on terraces and patios. It will flower in full sun, partial shade, or total shade, and requires well-drained soil (if constantly kept damp it may succumb to fungal infection), moderate water, moderate fertilizer, and a climbing structure (whether a trellis or another plant is secondary). Propagation is most commonly done with cuttings/ clones.
It is widely planted in California and also particularly in the Southeastern United States, where its hardiness, confined to USDA Zones 8-10, the area of the former Confederate States of America, gives it the name confederate jasmine. It gets another of its common names, trader's compass, from an old Uzbekistan saying that it pointed traders in the right direction, provided they were of good character. It is also called star jasmine in Europe and Chinese jasmine or Chinese ivy in Asia.
This plant, and the variegated cultivar 'Variegatum', have gained the Royal Horticultural Society's Award of Garden Merit. Its irritating, milky latex-like sap makes it resistant to the depredations of Australian possums.
