Conospermum

Conospermum is a genus of about 50 species of flowering plants 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....read more on Wikipedia.
