Appearance
The button everlasting is a herbaceous perennial plant that grows to 20–50 cm high from a woody rootstock. The woolly stems rise vertically and are unbranched, and are topped by the yellow flowerheads in spring.
Naming
Jacques Labillardière described the button everlasting as ''Helichrysum scorpioides'' in 1806 from a specimen collected in Tasmania. The large genus ''Helichrysum'' was long recognised as polyphyletic and many of its members have been transferred to new genera. Botanist Paul Graham Wilson erected the new genus ''Coronidium'' for 17 species of daisy of the eastern states of Australia, and it was given its new name of ''C. scorpioides'' in 2008. Wilson suspects there may be several species within ''C. scorpioides'' as currently defined, but deferred formally splitting them when revising the genus.
Distribution
''Coronidium scorpioides'' is found from the Gibraltar Range in northern New South Wales, south through the eastern part of the state into Victoria and southeastern South Australia as well as Tasmania.
Habitat
It grows on heavier more fertile soils, such as brown clay or clay-loam, derived from basalt, or sandstone-shale, in open forest under such trees as narrow-leaved peppermint, Sydney peppermint, brown barrel, grey gum, manna gum or Blaxland's stringybark, or in more open woodland under scribbly gum and narrow-leaved apple. ''Coronidium scorpioides'' resprouts after bushfire, some plants taking as little as 16 weeks to flower.References:
