Helichrysum thianschanicum is a species of flowering plant in the family Asteraceae. It is commonly known as silver spike or icicle plant. [2] It is part of a large genus of over 500 species. [3]
Helichrysum thianschanicum is a small perennial shrub that grows 2 ft (61 cm) tall and wide. It resembles a lavender plant with basal branching and erect stems and is covered with 2 in (5 cm) long linear leaves that are covered with white pubescence. Yellow clusters of flowers are produced at the ends of stems during the summer. Up to 30 yellow, 1⁄3 in (8 mm) florets are in each cluster. In its native habitat, H. thianschanicum develops a finger-sized rhizome. [2]
Helichrysum thianschanicum was first described in 1880 by Eduard August von Regel. [1] The specific epithet refers to the Tian Shan mountain range of Central Asia. [2]
Helichrysum thianschanicum grows on gravelly slopes and sand dunes in its native range of western China (Xinjiang) and adjacent Kazakhstan. [2]
Helichrysum thianschanicum 'Icicles' is a cultivar commonly grown in the United States for its foliage. During the summer, yellow flowers are produced at the ends of the stems and are composed of up to 30 florets. They are not spectacular but do accent the gray-white foliage. H. thianschanicum is a perennial that originates from a mountain range with hot dry summers and cold dry winters and is difficult to grow in wetter climates. 'Icicles' is usually grown as an annual plant in gardens. It seems resistant to most insect problems. [2]
Timothy is an abundant perennial grass native to most of Europe except for the Mediterranean region. It is also known as timothy-grass, meadow cat's-tail or common cat's tail. It is a member of the genus Phleum, consisting of about 15 species of annual and perennial grasses.
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.
Gundelia or tumble thistle is a low to high (20–100 cm) thistle-like perennial herbaceous plant with latex, spiny compound inflorescences, reminiscent of teasles and eryngos, that contain cream, yellow, greenish, pink, purple or redish-purple disk florets. It is assigned to the family Asteraceae. Flowers can be found from February to May. The stems of this plant dry-out when the seeds are ripe and break free from the underground root, and are then blown away like a tumbleweed, thus spreading the seeds effectively over large areas with little standing vegetation. This plant is native to the eastern Mediterranean and the Middle-East. Opinions differ about the number of species in Gundelia. Sometimes the genus is regarded monotypic, Gundelia tournefortii being a species with a large variability, but other authors distinguish up to nine species, differing in floret color and pubescence. Young stems are cooked and eaten in the Middle-East and are said to taste like a combination of artichoke and asparagus.
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.

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.
