Primrose jasmine is a rambling, open evergreen shrub with long, slender, arching stems

Primrose jasmine is a rambling, open evergreen shrub with long, slender, arching stems that will climb like a sprawling vine if given support. Without support, it grows in a fountainlike mound 5-10 ft (1.5-3.1 m) in height and spread. The stems are square in cross section, and green, becoming woody with age. The glossy dark green leaves are opposite and divided into three leaflets, each 1-3 in (2.5-7.6 cm) long. The fragrant trumpet shaped flowers are borne in early spring and sporadically into summer. They are semidouble with 6-10 petals, almost 2 in (5.1 cm) across, and sweetly fragrant. Primrose jasmine is very similar to the closely related winter jasmine (J. nudiflorum), but is less cold hardy, has larger, fragrant flowers, and blooms a little later in the season.
