The genus Helichrysum consists of an estimated 600 species of flowering plants in the sunflower family (Asteraceae). The type species is Helichrysum orientale. They often go by the names everlasting, immortelle, and strawflower. The name is derived from the Ancient Greek words ἥλιος and χρῡσός.
Xerochrysum bracteatum, commonly known as the golden everlasting or strawflower, is a flowering plant in the family Asteraceae native to Australia. Described by Étienne Pierre Ventenat in 1803, it was known as Helichrysum bracteatum for many years before being transferred to a new genus Xerochrysum in 1990. It is an annual up to 1 m (3.3 ft) tall with green or grey leafy foliage. Golden yellow or white flower heads are produced from spring to autumn; their distinctive feature is the papery bracts that resemble petals. The species is widespread, growing in a variety of habitats across the country, from rainforest margins to deserts and subalpine areas. The golden everlasting serves as food for various larvae of lepidopterans, and adult butterflies, hoverflies, native bees, small beetles, and grasshoppers visit the flower heads.
Xerochrysum is a genus of flowering plants native to Australia. It was defined by Russian botanist Nikolai Tzvelev in 1990, preceding Bracteantha which was described the following year. A 2002 molecular study of the tribe Gnaphalieae has indicated the genus is probably polyphyletic, with X. bracteatum and X. viscosum quite removed from each other.
Acacia binervia, commonly known as the coast myall, is a wattle native to New South Wales and Victoria. It can grow as a shrub or as a tree reaching 16 m in height. This plant is reportedly toxic to livestock as the foliage (phyllodes) contain a glucoside which can produce hydrogen cyanide if cut.
Podotheca is a genus of flowering plants in the tribe Gnaphalieae within the family Asteraceae. All species are endemic to Western Australia, except for Podotheca angustifolia which occurs across the south of Australia.
Leptorhynchos is a genus of annual or perennial herbs in the family Asteraceae. All species are endemic to Australia. These include:
Chrysocephalum semipapposum, commonly known as clustered everlasting is a perennial shrub native to Australia. Clustered everlasting belongs to the family Asteraceae. C. semipapposum produces terminal flowers heads in clusters, mainly between spring and early summer with silver-grey appearing stems and branches. It grows up to 40cm high and 60 cm high, although there have been some varieties which can grow up to 1 m. C. semipapposum is often confused with Chrysocephalum apiculatum or 'yellow buttons', due to their similar appearances. C. semipapposum has 4 different subspecies, however they lack distinctive qualities and are often hard to identify. C. semipapposum is endemic to Australia and can be found in multiple states, most notably within Victoria. The plant is found in a variety of habitats including dry rocky regions. Clustered everlasting often grows sparsely and is rarely found in abundance and can be mistaken for a weed. Clustered everlasting has many uses, including as a source of nectar for butterflies, cut flowers or as an addition to a garden.
