Description

Grevillea asparagoides is a dense, prickly shrub that typically grows to a height of 0.5–2 m (1 ft 8 in – 6 ft 7 in) and has hairy branchlets. Its leaves are 18–36 mm (0.71–1.42 in) long and have three to five lobes, each usually further divided, the end lobes linear or awl-shaped, sharply-pointed, 5–20 mm (0.20–0.79 in) long and 0.8–1.4 mm (0.031–0.055 in) wide with the edges rolled under. The flowers are arranged along a rachis 25–60 mm (0.98–2.36 in) long, and are pink to reddish-pink with a red style. The pistil is 30–37 mm (1.2–1.5 in) long with a sac-like perianth. Flowering occurs from July to December and the fruit is a follicle 13–17 mm (0.51–0.67 in) long.[2][3]

Taxonomy

Grevillea asparagoides was first formally described in 1856 by botanist Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis from specimens collected by James Drummond in the Swan River Colony.[4][5] The specific epithet (asparagoides) is derived from a passing resemblance of the foliage to that of asparagus.[6]

Distribution and habitat

This grevillea geos in heathland and shrubland in scattered populations between Perenjori, Wongan Hills and Bindi Bindi in the Avon Wheatbelt biogeographic region.[2][3]

Conservation status

Grevillea asparagoides is listed as "Priority Three" by the Government of Western Australia Department of Biodiversity, Conservation and Attractions,[3] meaning that it is poorly known and known from only a few locations but is not under imminent threat.[7]

Use in horticulture

This species requires a well-drained soil and full sun. Propagation is from cuttings; grafting on the east coast of Australia may be required to ensure greater reliability.[6]
