Jasminum mesnyi is a scrambling evergreen shrub growing to 3 m (10 ft) tall by 1–2 m (3–7 ft) wide, with fragrant yellow flowers in spring and summer. The form usually found in cultivation has semi-double flowers.[2] It is not frost-hardy. With suitable support it can be grown as a slender climber, though in confined spaces it will require regular pruning.[2][4][5][6]

Jasminum mesnyi has gained the Royal Horticultural Society's Award of Garden Merit.[7][8]
