Weeping bottlebrush
Melaleuca viminalis, family Myrtaceae
A red-flowered Australian tree with weeping branches and bottlebrush blooms
Weeping bottlebrush is a shrub or small tree native to eastern Australia, known for its bright red cylindrical flower spikes and drooping foliage. It grows along watercourses and is widely planted in gardens and as a street tree in many countries.
- Bright red cylindrical flower spikes resemble bottle brushes
- Grows naturally along streams in eastern Australia
- Helps prevent riverbank erosion with its dense root mat
- Flowers mainly September to December in its native range
- Many garden cultivars bred for compact or weeping forms
What does Weeping bottlebrush look like?
This plant grows as a multi-trunked shrub or small tree up to 10 metres tall, with hard, furrowed bark and long, narrow leaves. Its most striking feature is the bright red flower spikes, shaped like bottle brushes, 4 to 10 centimetres long, made of dense clusters of stamens. The branches often hang downward, giving it a weeping appearance.
Where does Weeping bottlebrush come from?
First described in 1788 as Metrosideros viminalis, it was later moved to the genus Melaleuca. Though now accepted under that name by some authorities, it is still widely known as Callistemon viminalis in Australia. It originates from stream banks and river edges in eastern Australia, from Queensland down into northern New South Wales.
When and how Weeping bottlebrush blooms
It flowers mainly in spring and summer, from September to December in Australia, but may bloom at other times too. It thrives in full sun and most soil types, tolerates shade with fewer flowers, needs regular water when young, and handles drought once mature. It does not survive frost or salty sea winds.
How Weeping bottlebrush is used
Commonly grown in gardens and used as a street tree, it serves well as a screen or windbreak. Its dense roots help stabilise riverbanks and reduce erosion. Many cultivated forms exist, selected for size, shape, or flowering, and it is planted far beyond its native range, including in parts of Africa, India, and the Americas.
Kinds of Weeping bottlebrush
Two subspecies are recognised. The typical form is multi-trunked and often flowers year-round. The other, subsp. rhodendron, is a single-stemmed tree reaching 35 metres, found only near Injune in Queensland, and flowers mostly in September and October.
What Weeping bottlebrush means
Its name comes from the Latin 'viminalis', meaning long and slender branches. Though not tied to specific festivals or faiths, it is valued in landscaping and environmental planting for its hardiness and role in protecting waterways. It supports nectar-feeding birds and insects.
