Star jasmine

Trachelospermum jasminoides

Evergreen twining climber with dark glossy leaves and clusters of small white pinwheel-shaped flowers carrying intense vanilla-jasmine fragrance through summer. Not a true jasmine — in the dogbane family.

Growing notes

  • Plant against walls and on pergolas in mild climates — fragrance carries on warm afternoons and evenings, peaks in early summer
  • Evergreen — provides year-round wall structure unlike true Jasminum which is deciduous in cool climates
  • Distinct from the true jasmines (Jasminum spp.) — Trachelospermum is in the Apocynaceae and exudes milky sap from cut stems
  • Tougher and more drought-tolerant than true jasmines once established
