Between 12 and 20 species of evergreen shrubs from Australia. They are prostrate to erect, with alternate leaves and axillary clusters or racemes (sometimes solitary) of pea-shaped flowers in shades of blue or purple.
The small species appear to be largely untried outside their native land, but they are decidedly attractive and worthy of alpine house room. H. purpurea var. montana might even be worth trying outside where frosts are not severe. Best in well drained, humus-rich soil in a sunny site, though some shade is tolerated. Propagation by seed in spring or cuttings in late summer.
