Conospermum is a genus of about 50 species in the family Proteaceae that are endemic to Australia. Members of the genus are known as smokebushes – from a distance, their wispy heads of blue or grey flowers resemble puffs of smoke. They have an unusual pollination method that sometimes leads to the death of visiting insects. They are found in all Australian states, though most occur only in Western Australia. Smokebushes are rarely cultivated, though the flowers of several Western Australian species are harvested for the cut flower industry.
Conospermum species are shrubs or small trees ranging in height from 0.3 metres (1 ft) to 4 metres (10 ft). The leaves are usually simple, linear or egg-shaped and have margins without teeth. The flowers have both male and female parts, are arranged in heads or spikes of a few to many flowers and are white pink, blue, grey or cream-coloured. The fruit is a small nut usually with a fringe of hairs at its base.[1][2]
