Plant Identification

Genus: Trachelospermum
Family: Jasminoides
Plant type: Woody, evergreen climber
Variety: Common names include Star Jasmine and Confederate Jasmine.
Note: Star jasmine is a woody, evergreen climber with rich, dark green leaves which (may) turn bronze in winter. From mid to late summer, pure white, fragrant flowers are produced. It can be grown against a wall in milder climates or in a greenhouse or conservatory in areas prone to severe frosts.

Plant Requirements

Light preference: Full sun or semi shade. Shade from direct sunlight may be needed in some situations to protect the leaves from sun scorch (leaves may turn bright red).
Watering: Water well during the growing season and less in winter.
Soil requirements: Enjoys rich well composted fertile soil with good drainage. It prefers neutral to alkaline soil conditions, but will grow in slightly acid soils.
Fertilisation: Fertilise with a general fertiliser in spring. Does well with a compost top dressing.
Pruning: Maintenance pruning is done is spring, and consists simply of thinning out congested, weak or badly placed shoots. Wayward branches can be tied back to their supports to improve the shape of the plant. If your Star Jasmine has spindly stems without many growth buds, you can shorten the main stems by about one-third, to encourage vigour and bushing out.

Other Information

Insects: Relatively easy. May be attacked by aphids.
Diseases: Relatively disease free. According to the RHS, in heavy, damp or clay soils, or in soils with a fluctuating water table, Trachelospermum may be susceptible to Phytophthora root rots.
Propogation: Star jasmine can be propagated by layering in spring, and also from semi-ripe cuttings in summer and autumn.
