Red callistemon


Bottlebrushes (Callistemon spp.) are among the hardiest of Australian native plants.

They are long lived, require minimal maintenance and are almost impossible to kill. The flowers attract native birds, especially honey eaters, and reward the gardener with extraordinary amounts of colour. The original bottlebrushes available to gardeners were all bold red but flower colours now range from red to pink, mauve, cream and green.

Plant details

Common name: Bottlebrush. The name derives from the plant’s flowers, which look like brushes for cleaning bottles.

Botanic name: Callistemon spp. The name is derived from the Greek words kallos, meaning beauty, and stemon, meaning stamen, describing the coloured stamens, the showy part of the flowers.

Best climate: Bottlebrush grow in all but the driest areas of Australia. They need a warm spot in cool and mountain districts.

Best look

A bottlebrush is a good addition to almost any Australian garden. They also look great as a hedge, screen plant or street tree.

Good points

• Sensational spring colour
• Extremely hardy and long lived (bottlebrush flower year after year and can live for 20 to 40 years if given the right climatic and growing conditions).
• Low maintenance
• Thrive in damp, poorly drained soils but will also take a dry spot (but do not plant in water logged soils)
• Dwarf varieties are available
• Bird attracting


full sun, moist soils


Extremely hot, dry conditions or very cold conditions (although some species and cultivars are more tolerant than others to extremes of climatic conditions)

Down side

Can become open and straggly


For fertile varieties, snip off flowerheads at the base of the flower spike once the flower display has finished. This will encourage reflowering and result in a compact and attractive shrub or small garden tree. when plants become straggly, prune heavily after which new growth will flourish.
