The genus Callistemon has provided many fine horticultural specimens. They are generally noted for their flowers, adaptability and quick growth. The weeping bottlebrush Callistemon viminalis is a very fine example of the group. Callistemon viminalis occurs naturally on the east coast of Australia from Cape York to north-east New South Wales. It also extends to the tablelands and occasionally to the western slopes of the Great Dividing Range.
Petals are greenish or pale coloured, tiny, inconspicuous and in some cases deciduous.
Fruits are 5-6 mm in diameter and the seed is held for a few seasons. New growth emerges from the ends of the inflorescence and the young leaves have bronze-coloured hairs. Callistemon viminalis is extremely adaptable in cultivation. For optimum results it should be planted in moist well-drained soil in full or partial sun. The species is susceptible to frost damage while small and suitable protection is necessary.
