The bush violet produces masses of purple tubular flowers. It usually forms a rounded to spreading bushy shrub, 0.7 m high by 1 m wide, but sometimes also climbs into nearby trees and shrubs. New branches tend to root as they touch ground, so this plant can quickly spread. Evergreen, it has soft, shiny, dark green leaves. Flowers appear from late summer to autumn (February to April). The fruit is an explosive, club-shaped capsule, forming in autumn (March to May). Fast-growing and wonderfully easy-going, Barleria repens will adapt to a number of situations. Plant it in a large container, or on top of a low wall, where its foliage and flowers can cascade down and show to advantage. Mass plant it in partial shade under trees to form a groundcover, or plant along the edge of an informal border, or in a lightly shaded rockery. When planted in very deep shade it tends to become lanky and untidy and does not produce as many flowers. Always provide good, light, well-drained soil and plenty of compost and other organic material. Spread a layer of mulch on the surface of the soil after planting, and renew regularly. Water well in summer, but much less in winter. Plants thrive when fed with slow release 3: 1: 5 at intervals of 6-8 weeks (throughout growing season). Prune the plant back hard after flowering (at the end of autumn/winter) to keep it neat.
Pest-free and fairly frost-tolerant, it can take sun or light shade, and can handle temperatures ranging from about -2°C to 36°C.
