Olearia axillaris
''Olearia axillaris'' is a shrub of the Asteraceae family, found in coastal areas of Australia. Commonly known as the coastal daisybush, or wild rosemary, it was one of the first Australian edible plants to be recognised as such by Europeans.
==Description==
The species is an erect shrubby herb growing to 2 metres high, many branched, densely covered with small leaves, and has a silvery green appearance. It is readily identifiable, by its height, when amongst the vegetation venturing onto dune systems - pioneer plants. It is tolerant of strong winds, salt, and poor soils.
The leaves are small and many, in whorled arrangement at the stem, and covered in fine white hairs which contribute to the silvery colour of the shrub. These are about 12 mm long and may be 1 – 3 mm across, linear in shape, having a margin rolled toward the reverse, and are fragrant when crushed. Older leaves may lose the woolly covering and become smooth and green.
The yellow florets are supported by white bracts at the flowerhead. The fruit produced are achenes, 1.5 – 2 mm long, the pappus are bristles twice this length; this assists in the dispersal of the seeds by wind.
