Olearia phlogopappa, the dusty daisy-bush, is a species of flowering plant in the family Asteraceae.[2] It occurs in open forest, woodland, heath and coastal shrubland in New South Wales, Victoria, and Tasmania.[3][4]
Description
Oleraia phlogopappa grows to between 0.3 and 3 metres in height.[5] The leaves are quite variable, but are usually grey-green with minute hairs on the underside which impart a whitish or yellowish appearance.[5] The leaf margins are often bluntly toothed.[5] White, pink or mauve "daisy" flower heads around 20–25 mm in diameter are mainly produced in spring and early summer.[3]
Taxonomy
The species was first formally described by Jacques Labillardière in 1806 in Novae Hollandiae Plantarum Specimen and named Aster phlogopappus.[1] In 1836 the species was transferred to the genus Olearia by Augustin Pyramus de Candolle in Prodomus.[1]
There are 6 varieties which are currently recognised:[1]
- O. phlogopappa var. angustifolia (Hook.f.) W.M.Curtis
- O. phlogopappa var. brevipes (Hook.f.) W.M.Curtis
- O. phlogopappa var. flavescens (Hutch.) J.H.Willis
- O. phlogopappa var. microcephala (Hook.f.) W.M.Curtis
- O. phlogopappa (Labill.) DC. var. phlogopappa
- O. phlogopappa var. salicifolia (Hook.f.) W.M.Curtis
Cultivation
The species withstands moderate frost and drought, but prefers moist conditions and a well drained soil in a sunny or partially shaded position.[3] Pruning is required to stop plants becoming spindly.[3] Cuttings are the usual method of propagation as seed may be unreliable.[3]
