Grevillea robusta is a tree that can reach 12 metres in height. It adapts to different ecological conditions and is found between 500 and 2000m altitude where annual rainfall ranges from 800 to 1500mm. Widely planted in warm temperate, subtropical or tropical regions for shade or agroforestry, Grevillea robusta has naturalised and become invasive in several countries (Hawaii, Australia, Mauritius, the Caribbean, Brazil and French Polynesia). Its leaves produce an allelopathic substance which inhibits the establishment and development of other species.
