Rhodanthe humboltiana, commonly known as the golden cluster everlasting, [2] is a flowering annual in the family Asteraceae. It is a small, upright, branching plant with yellow flowers, and is endemic to Western Australia.
Rhodanthe humboldtiana is an upright or ascending, bushy annual to 30 cm (12 in) high with woolly or almost smooth stems arising from the base. The leaves are sessile, narrow, linear, greyish-green, 10–20 mm (0.39–0.79 in) long, 0.5–2 mm (0.020–0.079 in) wide, and the apex rounded. The flower heads are 1–2 cm (0.39–0.79 in) in diameter, borne singly at the end of leafy branchlets. The bracts are arranged in several rows, white, dry, pointed, mostly upright or the inner bracts spreading, corolla about 5 mm (0.20 in) long, toothed and the 20-50 florets yellow. The flowering occurs from August to January but mostly in spring, and the fruit is a rounded achene about 3 mm (0.12 in) long and covered with soft, silky, weak hairs. [2] [3]
This species was first described as Helipterum humboldtianum in 1829 by Gaudich. [4] In 1992, Paul G. Wilson changed the name to Rhodanthe humboldtiana and the description was published in Nuytsia . [5] [6] The specific epithet (humboldtiana) is named in honour of Alexander von Humboldt. [7]
The Golden cluster everlasting grows on sand plains and heathland, sometimes with limestone from north of Perth to Shark Bay in Western Australia. [2] [8]
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 40 cm 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.
