Hardenbergia comptoniana

Lilac Vine
Fabaceae (Leguminosae)
Evergreen, Vines


Native to Australia. Grow at moderate rate to 10 ft., climbing by twining stems. Attractive flowers shaped like sweet peas bloom from late winter to early spring, carried in clusters of several to many. Need light, well-drained soil. Provide support for climbing and cut back after bloom to prevent tangling. Good against trellises in large containers (use soil mix rich in organic matter).
