Grevilleas are closely related to the genus Hakea, the genus gives its name to the subfamily Grevilleoideae. Many species of grevilleas are popular garden plants, especially in Australia but also in other temperate and subtropical climates. Many grevilleas interbreed freely, and some specially picked hybrids have been grown for sale. Among the best known are Grevillea 'Robyn Gordon', a small shrub up to 1.5 metres high and wide which can flower 12 months of the year in subtropical climates.
