Callistemon Citrinus commonly known as Lemon Bottlebrush or Red Bottlebrush. It is a useful and attractive evergreen shrub for urban, cottage, and coastal garden borders. Botanically known as Callistemon Lanceolatus or Callistemon Citrinis, this upright, spreading evergreen shrub is a native of Australia. Its 10-centimetre evergreen foliage is lance-shaped, mildly aromatic, and covered in fine silky hair. New shoots are silvery, before maturing to mid-brown. The showy spiky red flowers resemble a bottle brush – hence its common name Bottlebrush Plant. The red flowers are semi-open spikes measuring 10 cm in length. In late summer they mature into woody seed capsules which remain on the plant for years. In winter, the foliage and capsules remain on the plant and look attractive covered in frost. They also provide hibernation areas for over-wintering insects. Bottlebrush is a great border filler that provides year-round interest.

It enjoys most types of soil so long as it is free-draining. Plant yours in full sun to partial shade and water well until established. A thick layer of mulch around the roots seals in moisture, suppresses weed competition, and provides nutrients for a healthy show of lemony-bottlebrush flowers in spring. There is no need to prune a bottlebrush as they naturally grow erect and spreading, but you can reduce the size or remove dead branches in late winter or early spring.
