Coronidium elatum
Coronidium elatum, commonly known as the white paper daisy or tall everlasting, is a perennial herbaceous shrub in the family Asteraceae found in open forests in eastern Australia. A woody shrub tall, it has white flowers which appear in spring. It was known as "Helichrysum elatum" for many years until it was finally reviewed in 2008. Description. The plant is a woody shrub or subshrub with an erect habit reaching anywhere from high. The ovate to elliptic leaves are up to long with entire or wavy (sinuate) margins, and sit on 1–2 cm long petioles. The petioles and  leaf undersides are covered in white hair, the upper leaf surfaces less so. The flowers appear from June to November, with plants most floriferous in September. The disc is yellow and bracts are white, the flower heads in diameter. Taxonomy. The tall everlasting was collected by the English botanist and explorer Allan Cunningham and described by him in Augustin Pyramus de Candolle's 1838 work "Prodromus Systematis Naturalis Regni Vegetabilis" as "Helichrysum elatum", the species name being the Latin adjective "elatus" "tall". 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. elatum" in 2008. In the same journal, Wilson described three subspecies and the names are accepted by the Australian Plant Census: Distribution and habitat. "Coronidium elatum" is found from the southeastern corner of Queensland, along the eastern coastal regions of New South Wales and into the tip of eastern Victoria. It grows on shale, basalt or sandstone-based soils which are high in nutrients, in open forest or rainforest  margins, under such trees as brown barrel ("Eucalyptus fastigata"), mountain grey gum ("E. cypellocarpa"), messmate ("E. obliqua") or white stringybark ("E. globoidea"). It can be abundant after bushfires and on disturbed ground. Two of the subspecies are highly restricted in distribution. Subspecies "vellerosum" is endemic to the summit of Mount Warning and subspecies "minus" is found only near Point Lookout in New England National Park. . Uses. "Coronidium elatum" is a highly regarded and underutilised garden plant, producing abundant flowers and growing quickly. It is frost hardy and grows in full or part sun. It can be propagated from seed, or  by cuttings, although these are susceptible to rotting. One cultivar, "Coronidium elatum" 'Sunny Side Up', has been released commercially.
