Conospermum caeruleum, commonly known as blue brother, is a shrub in the family Proteaceae and is endemic to the south west of Western Australia. It is a prostrate shrub with small, dense heads of blue, rarely pink flowers and usually grows in heavy soils subject to flooding.
It grows as a prostrate or straggly shrub usually growing to a height of about 0.5–1.0 metre (2–3 ft) and a spread of up to 2 metres (7 ft). The leaves are clustered at the base of the stem, have a stalk 5–60 millimetres (0.2–2 in) and a leaf blade that is thread-like to egg-shaped and 14–148 millimetres (0.6–6 in). The leaves have prominent veins and end abruptly in a sharp point. The flowers are arranged in dense clusters of up to 18 tube-like blue flowers, each about 5–8 millimetres (0.2–0.3 in) long. Flowers appear between July and October and are followed by the fruit which is a nut about 2 millimetres (0.08 in) long and 2–2.5 millimetres (0.08–0.1 in) wide.[2][3][4]
Conospermum caeruleum was first formally described in 1810 by Robert Brown and the description was published in Transactions of the Linnean Society of London from a specimen collected near "King George's Sound, west coast of New Holland".[5][6] The specific epithet (caeruleum) is a Latin word meaning "sky-blue".[7]
Six subspecies are recognised by the Australian Plant Census as at November 2020:
Conospermum caeruleum occurs from Busselton to east of Albany[2] in the Avon Wheatbelt, Esperance, Geraldton Sandplains, Jarrah Forest, Mallee, Swan Coastal Plain and Warren biogeographical regions of Western Australia[14] growing on sand, sandy peat, stony clay, laterite or granite in areas that are wet in winter.[15]
Conospermum species, especially the Western Australian ones are difficult to cultivate.[16]
Conospermum caeruleum is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[14]
