It usually grows to between 0.5 and 2.5 metres in height and 4 metres wide.[2] Yellow, red or black "toothbrush" flowers are produced between May and November.[1]

The species was formally described by botanist Carl Meissner in Plantae Preissianae in 1845.[3]

The Latin specific epithet hookeriana refers to Sir Joseph D. Hooker.[4]

Three subspecies are currently recognised:

  • G. hookeriana subsp. apiciloba (F.Muell.) Makinson[5]
  • G. hookeriana subsp. digitata (F.Muell.) Makinson[6]
  • G. hookeriana Meisn. subsp. hookeriana[7]

Cultivation

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.[8]

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.[8] It requires good drainage and prefers a sunny or partially shaded position and has moderate frost resistance.[8] Propagation is from semi-mature cuttings or seed.[8]
