Grevillea hookeriana
Red toothbrushes (Grevillea hookeriana) is a spreading to erect shrub from south-west Western Australia, grown for its toothbrush-shaped red, black or yellow-green flowers. It is comparatively rare in cultivation and needs good drainage and dry summers.
Grevillea hookeriana, commonly known as red toothbrushes or Hooker's grevillea, is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is a spreading to erect shrub, usually with linear leaves or deeply divided leaves with linear lobes, and toothbrush-shaped groups of red, black or yellowish green flowers, the style maroon to black.
A cultivar known as G. 'Red Hooks' (often erroneously referred to as G. hookeriana or G. hookerana) has been in cultivation for many years. It is a hybrid of G. hookeriana and G. tetragonoloba. G. hookeriana is comparatively rare in cultivation, and less vigorous than the cultivar. It is best suited to a climate where the summers are dry.
It requires good drainage and prefers a sunny or partially shaded position and has moderate frost resistance. Propagation is from semi-mature cuttings or seed.
Hooker's grevillea is widespread in the south-west of Western Australia, where it grows in heath or shrubland, mainly between Three Springs, Mount Churchman (near Karroun Hill Nature Reserve), Coolgardie and Katanning. Subspecies apiciloba is mostly found in the centre of the species' range, subsp. digitata in the north-west of the species' range and subsp. hookeriana in the area between Coorow, Katanning, Newdegate and Merredin.
