DC. }}Olearia ramulosa, the twiggy daisy-bush, is a species of flowering plant in the family Asteraceae.[2] It occurs in New South Wales, Victoria, South Australia and Tasmania.[2]Jacques Labillardière described the twiggy daisy bush as Aster ramulosus in 1806, in volume 2 of his Novae Hollandiae Plantarum Specimen, from material collected in Tasmania.[3] The species name, derived from the Latin rama "branch", means having many small branches.[4] German botanist Christian Gottfried Daniel Nees von Esenbeck called it Diplostephium ramulosum in 1832,[5] and Swiss botanist Augustin Pyramus de Candolle called it Eurybia ramulosa in 1836.[6] Alternative common names are oily bush and water cypress.[7] Olearia ramulosa is a shrub that reaches 1.6 m in height. The narrow leaves are alternately arranged along the stems and measure 2–8 mm long by 0.8–2.5 mm wide with entire margins. The flowers appear from October to May. The daisy-like flower heads are 1–2 cm in diameter, with 2–13 white or mauve rays and a central yellow disc.[2] Flower heads can appear in great numbers and be highly conspicuous.[4]The plant is eaten by caterpillars of the moth species Amelora milvaria.[8] Bees, beetles, and less commonly flies and wasps have been recorded visiting flowers in a Tasmanian field study.[9] Olearia ramulosa can be propagated by seeds or cuttings of new growth that has hardened. It can be grown in dry or temperate climates and is frost-hardy in sunny or part-shaded spots. Pruning can invigorate it and it can be grown as a low hedge.[4]References1. ^{{cite web|url=http://www.anbg.gov.au/cgi-bin/apni?TAXON_NAME=OLEARIA+RAMULOSA|title=Olearia ramulosa |accessdate=2009-03-22 |work= Australian Plant Name Index (APNI), IBIS database|publisher = Centre for Plant Biodiversity Research, Australian Government, Canberra}} {{Taxonbar|from=Q7086009}}2. ^1 2 {{cite web |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Olearia~ramulosa= |title=Olearia ramulosa (DC.)
