Myrtle (Myrtaceae)
Callistemon citrinus, also known as bottlebrush, belongs to the myrtle family (Myrtaceae) and originates from Australia. The evergreen shrub or small tree usually reaches a height of 2–5 metres and is known for its characteristic cylindrical red inflorescences, which resemble bottle brushes. These consist of numerous long stamens that attract insects, birds and, above all, nectar-feeding birds. The flowering period is long and often repeats several times a year.
The narrow, leathery leaves exude a lemon-like scent when crushed – hence the species name “citrinus”. After flowering, woody capsule fruits form, which often remain attached to the branch for years. Its high adaptability is botanically interesting: Callistemon citrinus tolerates sun, heat, short periods of drought and even pruning, which is why it is cultivated in many countries as an easy-care ornamental plant in parks and gardens.
In traditional Australian medicine, infusions made from the leaves were used to treat colds and infections. Today, the plant is widespread worldwide and is a popular design element due to its striking flowers. Symbolically, the bottlebrush often stands for purity and vitality, and in Australia it is also considered a symbol of the native flora.
