Hook. }}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][3] DescriptionOleraia phlogopappa grows to between 0.3 and 3 metres in height.[4] The leaves are quite variable, but are usually grey-green with minute hairs on the underside which impart a whitish or yellowish appearance.[4] The leaf margins are often bluntly toothed.[4] White, pink or mauve "daisy" flower heads around 20–25 mm in diameter are mainly produced in spring and early summer.[5]TaxonomyThe 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]
CultivationThe species withstands moderate frost and drought, but prefers moist conditions and a well drained soil in a sunny or partially shaded position.[5] Pruning is required to stop plants becoming spindly.[5] Cuttings are the usual method of propagation as seed may be unreliable.[5] CultivarsA number of cultivars are commercially available including:[1][6]
Another cultivar, 'Havering Blush', is a hybrid between Olearia phlogopappa and Olearia lirata.[6] References1. ^1 2 3 4 {{cite web|url=http://www.anbg.gov.au/cgi-bin/apni?TAXON_NAME=Olearia+phlogopappa|title=Olearia phlogopappa |accessdate=2009-06-28 |work= Australian Plant Name Index (APNI), IBIS database|publisher = Centre for Plant Biodiversity Research, Australian Government, Canberra}} {{Taxonbar|from=Q7086006}}2. ^{{cite web | url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Olearia~phlogopappa= |title=Olearia phlogopappa (DC.)
