Star jasmine is an evergreen vine from East Asia with sweet-smelling white flowers in spring, widely planted in California and the Southeast. Despite the name, it isn't a true jasmine; it belongs to the dogbane family. It's also called Confederate jasmine.

Appearance

Growth form
A woody, evergreen climbing vine, usually up to about 10 ft (3 m). It twines around supports and puts out on damp surfaces. Cut stems ooze milky sap.
Leaves
Opposite, glossy, dark green, oval to lance-shaped leaves about 1½–3 in (4–8 cm) long that often turn bronze in winter.
Flowers
Fragrant white flowers about ¾–1 in (2–2.5 cm) across, with five petal-like lobes, in loose clusters from spring into early summer.
