Grevillea trachytheca, commonly known as vanilla grevillea[2] or the rough-fruit grevillea is a shrub of the genus Grevillea native to an area in the Mid West and Gascoyne regions of Western Australia.[3]

Description[]

The erect to spreading evergreen shrub typically grows to a height of 0.6 to 2 metres (2.0 to 6.6 ft) and has non-glaucous branchlets. It has simple, flat, linear tripartite mid-green leaves with a blade that is 15 to 35 millimetres (0.59 to 1.38 in) and 1 to 2 millimetres (0.04 to 0.08 in) wide. It blooms between May and October and produces a terminal raceme irregular inflorescence with white or cream strongly-scented flowers[4] and white or cream styles. Later it forms pitted, ellipsoidal or ovoid and glabrous fruit that are 11 to 14 mm (0.4 to 0.6 in) long.[3] It regenerates from seed only and is very closely related to Grevillea crithmifolia, which has a shorter conflorescence and divided leaves.[5]

Taxonomy[]

Grevillea trachytheca was first described the botanist Ferdinand von Mueller in Fragmenta phytographiae Australiae in 1888.

Distribution[]

It is commonly found amongst medium to low trees in shrubland it is restricted to areas near Kalbarri and the lower part of the Murchison River. It grows in calcareous sandy soils.[5]

Cultivation[]

Grevillea trachytheca is used in gardens with dry soils that is suitable in a Mediterranean climate and in coastal areas, it can be used as an informal hedge, border planting or as a windbreak. It prefers full sun and can tolerate wind and salt.[2][4]
