Winter jasmine (Jasminum nudiflorum) is a slender, deciduous shrub native to China (Gansu, Shaanxi, Sichuan, Xizang (Tibet), Yunnan). It is widely cultivated as an ornamental and is reportedly naturalized in France and in scattered locations in the United States (Texas, Oklahoma, Georgia, Tennessee, Maryland and New Jersey).[2][3][4]
Description
It grows to 3 m (10 ft) tall and wide,[5] with arching green shoots and opposite, pinnate, dark green leaves. Each leaf is divided into three oval-oblong leaflets which are about 3 cm long.[4][6]
As its name suggests, in the Northern Hemisphere winter jasmine flowers from November to March. The solitary flowers, often appearing on the bare stems (hence the Latin nudiflorum, literally "naked flower")[7] have six petals and are bright yellow, or white, about 1 cm across, appearing in the leaf axils. It likes full sun or partial shade and is hardy.
Jasminum nudiflorum is valued by gardeners as one of the few plants that are in flower during the winter months. It is frequently trained against a wall to provide extra warmth and shelter,[8] but also lends itself to groundcover.[5] It tolerates hard pruning and should be pruned in spring immediately after flowering; regular pruning will help to prevent bare patches. It can also be grown as a bonsai and is very tolerant of the wiring methods. It can be propagated using the layering technique.

It is known as rui guo yuan wei in Pidgin.[9]
