That is where Callistemon is from: the South-East of Australia and Tasmania. This flowering evergreen grows lovely red plumes that are up to 10 cm long and has beautiful leather-like green leaves.
This plant truly adds to your terrace, balcony or garden. Callistemom had best be treated like an orangery plant. Of course you could plant it in the full soil, but in wintertime it does need protection against the frost. Orangery plants had best be placed on a frost-free spot where they can hibernate in the winter.
The name Callistemon is derived from the Greek words kallos (beauty) and stemon (stamen).
Your Callistemon is not very fond of calcium-rich soil. When you repot your plant or when you add some extra soil, you had best add a little peat, as well.
After the flowering season, Callistemon can be pruned back up to about one-third. Try to avoid cutting out its wooden parts.
This species of Callistemon flowers from April until September.
