Acacias also occur in Africa, South America and throughout other warm areas of the world. Flowers and Foliage Wattles show a range of foliage and flower types. The foliage colour of wattles ranges from light or dark green to blue or silver-grey. Flowering times of wattles vary greatly, with the bulk of species flowering in spring and summer. Other species flower during autumn and winter and, with careful selection, it is possible to have flowering wattles in the garden at all times of the year.
Flower heads vary in colour through cream, pale yellow to gold.
The flower heads of many species are delicately perfumed. Wattles as Garden Plants Wattles make excellent garden plants. They range from prostrate and low-growing species to larger shrubs and shade trees. Most respond to pruning immediately after flowering and, if carried out regularly, pruning can extend the life of the plant. The main pests are stem borers which can be controlled by probing with flexible wire or by injecting a few ml of alcohol into the holes.
