The species displays a high level of plasticity in its leaves, habit, and habitat preferences across its natural range. The height of the shrubby forms usually ranges between 1 and 2 metres but can reach 4 metres in some populations, while prostrate forms are also observed in their natural distribution, sometimes growing among shrubby forms. The flowers occur in terminal one-sided racemes, typical of what are commonly referred to as "toothbrush" grevilleas. They are red or occasionally yellowish-green. Flowering in South Australia is recorded as being between November and March, while in the Grampians in Victoria it extends from September to April. The foliage is usually lobed with sharp points on the lobes but some populations have leaves with nearly entire leaf margins.
