Beaufortia aestiva, commonly known as sand bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a dense, usually rounded shrub with small leaves and which bears yellow or red flowers in bottlebrush-like spikes near the ends of the branches in summer. It is similar to Beaufortia squarrosa but that is a smaller shrub which always has red flowers.
Description
Beaufortia aestiva is sometimes a dense, rounded shrub and others an open spreading one. It occasionally grows to a height of 4 metres (10 ft) but more usually 2 metres (7 ft). The leaves are egg-shaped with the narrower end towards the base, 4–11 millimetres (0.2–0.4 in) long and are arranged in alternating pairs (decussate), so that they form four rows along the stems.
The flowers are creamy orange-coloured to red and are arranged in heads 35–45 millimetres (1–2 in) in diameter, on the ends of branches which continue to grow after flowering. Flowering occurs from June to December, sometimes later and is followed by fruits which are woody capsules 7–9 millimetres (0.3–0.4 in) long.[1][2]
