About Bottlebrush
Callistemon citrinus, commonly known as Crimson Bottlebrush, is an evergreen shrub or small tree native to Australia. It is characterized by its striking, bright red, bottlebrush-shaped inflorescences, which bloom primarily in spring and summer. It is ideal for Mediterranean gardens, as a specimen plant, or for creating flowering hedges.
Native range
Southeastern Australia
Care tips
It requires full sun exposure for abundant flowering and optimal development. Watering should be moderate once established, tolerating periods of drought but benefiting from regular watering in summer. It prefers well-drained, slightly acidic to neutral soils, and a common mistake to avoid is waterlogging, which can lead to root rot.
