Callistemon salignus (MYRTCAEAE) Willow Bottlebrush, White bottlebrush

Callistemon salignus
A very large specimen in remnant scrub. A Gum Vine of considerable age is living on this tree, which has a girth of about 1m at the base. Photo: Robert Whyte

This small-medium tree has attractive narrow foliage and white papery bark. Drought resistant and quite hardy, although can be affected by frost. An excellent garden and street tree to 12 m tall. Mostly grows in low-lying river flats and damp creeks, rarely in dry areas; north from the Victorian border.

A characteristic and widespread tree in remnant dry rainforest and should be planted widely. Seed easy to collect, stays on the tree for a long time but often high up.

Leaves narrow-elliptic, mostly 6-9 cm long, 5-14 mm wide, attenuate at both ends, apex acute; midrib, marginal and lateral veins distinct. New growth purplish pink.

Was in some places known as Melaleuca saligna, previously thought to be a different species. The bark is as certainly papery as a Melaleuca.

With ideal conditions will grow up to 1200mm per year, and form an excellent weeping canopy within 5 years. Said to be prey to Saw Fly attack.
