Did you know
- The flower spikes look exactly like cylindrical bottle brushes, with hundreds of long red stamens packed tightly together — the petals themselves are tiny.
- Bottlebrush flowers are pollinated by birds, especially honeyeaters and lorikeets, which feed on the abundant nectar.
- Like many Australian natives, bottlebrush seeds are released from woody fruits only after exposure to fire — a fire-dependent reproductive strategy.
- Crushed leaves smell strongly of lemon and have been used in folk medicine and as an insect repellent.
- Bottlebrush is so widely planted as a street tree that it's become a familiar sight in warm climates worldwide, including California, the Mediterranean, and South Africa.
