Quick facts

About Bottlebrush

Callistemon rugulosus, commonly known as 'scarlet bottlebrush', is a perennial shrub or small tree native to Australia, renowned for its spectacular, bright red, brush-like flower spikes. Its leaves are narrow and aromatic, and its dense habit makes it ideal for hedges, screens, or as a standalone specimen in Mediterranean and subtropical gardens. It attracts pollinators such as hummingbirds and bees.

Care tips

It thrives in full sun for abundant flowering and prefers well-drained soil, though it tolerates a variety of substrates. Once established, it is quite drought-tolerant but appreciates regular watering during dry spells and in its juvenile stage. Prune after flowering to maintain shape and encourage new blooms; avoid waterlogging, as it can lead to root rot.
