Olearia subspicata, commonly known as spiked daisy bush[2] or shrubby daisy-bush,[3] is a species of flowering plant in the family Asteraceae and is endemic to continental Australia.

It is an erect shrub with more or less linear leaves and white and yellow, daisy-like inflorescences.

The heads or daisy-like "flowers" are arranged singly or in panicles on the ends of branches or in leaf axils on a peduncle about 9 mm (0.35 in) long and are 14–20 mm (0.55–0.79 in) in diameter with a narrowly conical involucre at the base.

[2][3][4][5][6] This daisy was first formally described in 1845 by William Jackson Hooker who gave it the name Eurybia subspicata in Thomas Mitchell's Journal of an Expedition into the Interior of Tropical Australia.

[10] Spiked daisy bush grows in shrubland, mallee and mulga and is widely distributed in Western Australia, South Australia, the southern parts of the Northern Territory, western New South Wales, Queensland and the far north-west of Victoria.
