Trachelospermum asiaticum aka Asiatic Jasmine

Trachelospermum asiaticum is an evergreen vine called Asiatic jasmine. It belongs to the dogbane family, Apocynaceae. Its native range runs from northern India to Japan and Borneo. It grows in woods, scrub, and thickets on hills. In forests, its stems wind around trees for support. Gardeners grow it as a climber or ground cover. North Carolina State reports fast growth, while Useful Tropical Plants lists slow growth.

Its size depends on how gardeners grow it. Ground cover reaches 1–2 feet (0.3–0.6 metres) tall. It spreads 10–12 feet (3–3.7 metres) across the ground. The RHS gives climbing plants a larger garden range. These reach 13–26 feet (4–8 metres) tall and wide. Other records describe stems reaching 33 feet (10 metres) long. The thin, tough stems twine around their supports. Paired leaves have a dark green, glossy surface. They feel leathery and have smooth edges. Each leaf has an oval or narrow egg shape. Some leaves turn bronze or red in fall.

Small, star-shaped flowers form clusters on side shoots. Their cream petals surround pale tan or yellow centres. The flowers have a sweet scent. Bloom runs from late spring into early summer. The leaves keep the plant green beyond its bloom season. It attracts songbirds and suits borders, slopes, and hanging baskets. Gardeners also train it over fences, trellises, and arbors. It can form a low hedge or screen. Coastal gardens benefit from its moderate tolerance of salt. It also tolerates deer browsing.

Grow it in sun or part shade with good drainage. It accepts clay, loam, sand, and chalk soils. Acid, neutral, and alkaline soils can all suit it. Fertile soil and shelter from cold winds support growth. It tolerates drought and dry to moist soil. North Carolina State lists USDA zones 7–11. The RHS rates it H4 for UK gardens. Useful Tropical Plants reports greater cold tolerance in suitable sites. Young plants need protection from cold winds. Prune in early spring to control its growth. Layering and semi-hardwood cuttings offer ways to raise more plants.

North Carolina State reports no major pest or disease problems. The RHS lists scale, mealybugs, and glasshouse red spider mites. Honey fungus may also affect the plant. Plants For A Future reports a limited food use. Young buds can be cooked, but their type is unclear. The source does not distinguish leaf buds from flower buds. It lists no known medicinal use or hazard. That does not establish safety for people or pets.
