Primrose Jasmine is an open evergreen shrub with long, slender, arching, square stems becoming woody with age, and dark green leaves, that can climb like a sprawling vine up to about 15 feet or more if given support.

More often it simply produces a large, messy shrub, reaching heights of 6 feet or more.

The leaves have three distinct leaflets and are bright green and smooth. The long stems will root wherever they touch the ground.

In the late winter through the spring, its flowers are a bright yellow color, but have very little smell.

In its native habitat of southwestern China, it is found in shrubberies and forests, usually on humus-rich soils, between 1,200 - 3,000 metres in the Himalayas. In valleys, ravines, thickets, woods, along rivers, meadows; at 1,800 - 4,000 metres.
