Olearia hookeri, commonly known as crimsontip daisybush,[2] is a species of flowering plant in the family Asteraceae and is endemic to Tasmania. It is a sticky shrub with small, narrowly linear leaves and white to bluish-purple and yellow, daisy-like inflorescences.
Olearia hookeri is a sticky, glabrous shrub that typically grows to a height of up to 2 m (6 ft 7 in). Its leaves are narrowly linear, 3–5 mm (0.12–0.20 in) long. The heads or daisy-like "flowers" are arranged singly on the ends of branchlets and are 20–25 mm (0.79–0.98 in) in diameter. Each head has eight to ten white to bluish-purple ray florets surrounding a slightly larger number of yellow disc florets. Flowering occurs from September to December and the fruit is a short, hairy achene, the pappus with bristles of different lengths.[2][3][4]
The species was formally described in 1853 by Otto Wilhelm Sonder who gave it the name Eurybia hookeri in Linnaea: ein Journal für die Botanik in ihrem ganzen Umfange, oder Beiträge zur Pflanzenkunde, based on plant material collected by Charles Stuart.[5][6] In 1867, George Bentham changed the name to Olearia hookeri in Flora Australiensis.[4][7]
Olearia hookeri grows on dry hills near Hobart and in shrubby woodland on the south and central-east coasts of Tasmania.[2]
This daisy bush is listed as "rare" under the Tasmanian Government Threatened Species Protection Act 1995.[2]
