Callistemon viminalis (Gaertn.) Loudon

Weeping Bottlebrush

Shrub or small tree to about 8 m tall, generally with pendulous branches. Leaves linear to narrowly elliptic with one side straighter than the other, 3-7 cm long, 3-7 mm wide. Flower spikes 4-10 cm long, 3-6 cm wide; mostly spring to early summer. Filaments bright red, fused into a ring at the base and shed as a unit, the anthers dark-coloured. Fruit 5-6 mm wide. Syn. C. speciosus of authors other than (Sims) Sw.

Widely grown, with various habit forms and numerous cultivars.This species and its cultivars are easily recognised by the flat-sided fruits and stamens that are united into a ring at the base (often shed as a unit).

C. glaucus, Albany Bottlebrush, from WA is occasionally cultivated; it has stamens fused into 5 irregular bundles, and brushes 5-7.5 cm wide.

CULTIVARS Most of the cultivars of Callistemon are selections or hybrids involving C. citrinus or C. viminalis. As the true origin is often uncertain, all cultivars are treated together here rather under particular species. In the absence of detailed descriptions, cultivars are frequently difficult to identify and names have often been incorrectly applied; many are no longer available and hybridisation is said to occur frequently. The following is a selection of the more popular cultivars grown in SE Australia.
