They are small evergreen shrubs with a messy but very decorative appearance that can reach 1 meter (3.28 feet) in height. The leaves are deep green in color and fold in half lengthwise. The showy violet flowers have no scent but are highly ornamental. They bloom in spring. They produce fruits in the shape of an oval capsule that are first green and then red. Bush violet is used for mixed borders, as isolated specimens, to form hedges or for covering groups. Barleria obtusa needs full sun or semi-shade exposure; do not expose it to temperatures below 5 ºC (41 ºF). In Mediterranean climates with hot summers it is better to place it in semi-shade. The soil can be a well-drained garden substrate with coarse sand and a good supply of organic matter (humus). Water moderately as they are resistant to drought; Bush violet needs a medium humidity. Fertilize with organic fertilizer at planting time and in autumn. Prune after flowering to maintain a compact appearance; It is advisable to gradually eliminate withered flowers to provoke the appearance of new ones. Barleria obtusa is a very resistant plant to pests and diseases. Bush violet propagates by seeds sown in spring or by cuttings set to root, in summer, in their final location. |
