Plant details

The bottle brush plant, Callistemon citrinus, bears dramatic crimson-red flower spikes, in contrast with dark green, aromatic foliage, in spring and summer. New foliage has a pink-red flush, but darkens with age.

Native to Australia, Callistemon citrinus thrives in warm, sheltered conditions, and is suceptible to frost damage. For best results, and the greatest flowering potential, grow in front of a sunny wall or in a container which you can bring indoors in autumn.

Hot to take cuttings from my bottle brush


I've had a Calistemon in the front garden of my house, it open to the elements year round, flowers every year. So contrary to all advice where it should grow its been in the garden for over ten years not against a wall or fence, and is thriving.
