Answer: Trachelospermum is the Star Jasmine. This vine's slender stems form dense tangled mats when grown as ground cover.
The smooth stems are reddish brown and exude a milky liquid when broken. The small leathery leaves are glossy deep green and arranged in opposite pairs along the stems. Leaves are about .5 inches long and from 0.5 to .75 inches in width. The small pinwheel-shaped flowers are light yellow and have a delightful jasmine-like fragrance.
As the species name indicates, Trachelospermum asiaticum is native to Asia, specifically Korea and Japan.
Prefers rich, well-drained soil but will succeed in most soils except those that are soggy. Has good salt tolerance and can be grown near, but not directly on, the beach.
Tolerates deep shade, but prefers moderately shady situations in hot summer climates. Can be grown in full sun if kept watered or temperatures are not extreme. When grown indoors, yellow star jasmine needs several hours of direct sunlight during winter.
Prefers moist, well drained soil but will tolerate less than ideal situations and can handle short periods of drought once established.
Hardiness: USDA Zones 8 - 10. Said to be hardier than Confederate jasmine (but probably not by much), this vine doesn't like extended freezes and cold winter winds will desicate and kill.
If you plant in a container you can move it to a frost-free place during the winter months and it should survive.
Hope this answers all your questions!
