Callistemon are commonly known as bottlebrush due to the shape of their flowers which are referred to as being apetalous, they actually lack petals and it is the showy stamens that make Callistemon a standout in any garden. The flowers drip nectar which makes them very attractive to nectar-feeding birds such as Lorikeets and irresistible to bees. The main flower flush occurs in spring from October through to summer depending on variety. Additional flushes of flowers will often occur following good rains.

Callistemon are the perfect plant for the forgetful or lazy gardener as they will tolerate almost any amount of neglect. Bottlebrush come in a range of shapes and sizes from prostrate groundcovers and compact shrubs to tall trees. All in a variety of flower colours from white, cream, green, red, scarlet, pink, mauve and lilac. Hybridising has expanded the colour palette in recent years with some truly stunning bottlebrush available. Variation in foliage shape and colour across the seasons is another reason why Callistemon are such popular garden plants.

Callistemon will grow in most soil types and some will even tolerate wet feet. Callistemon will grow in full sun or part shade but plants in full sun tend to produce more flowers with vibrant colour. Prune immediately after flowering to keep plants compact and floriferous. If plants become straggly they can be cut back heavily to encourage new growth, being tough plants they are very forgiving.

Bottlebrush with their rich nectar were an important energy source as an Aboriginal bush tucker food and their essential oils have been used in traditional medicine to treat a range of medical conditions.

A close relative to the Callistemon is the genus Melaleuca commonly known as paperbarks, on first appearance Bottlebrush and Melaleuca look very similar but there are botanical differences in their flowers.

Callistemon are worthy of a place in any suburban garden and can be used as specimen plants, for screening, low borders and hedging.
