Star Jasmine
Botanical Name: Trachelospermum jasminoides
Family: Apocynaceae
Origin: East Asia
Plant Type: Evergreen climber (vine)
Overview
Trachelospermum jasminoides is a superstar for Adelaide and coastal SA—dense, glossy foliage that bronzes to burgundy in winter, then explodes with highly fragrant white star flowers in late spring–summer (often a light encore in early autumn). Tough, tidy and versatile, it softens fences, pergolas and arches, or trails beautifully in large pots on an obelisk.
