Flowers appear in late spring to summer and are highly scented. Despite this, it is a very spectacular grevillea which should be more widely cultivated, particularly in areas with a Mediterranean-type climate of hot, dry summers and wet winters. In common with many species native to south Western Australia, G.candelabroides is not reliable on its own roots in humid, sub-tropical and tropical areas. It can, however, be grown successfully in those areas if grafted. It prefers a location in well-drained soils in full sun.
Cuttings are usually slow to strike.
