    It is harvested as a shadow tree and as a decoration tree, both because of its form and the green of the leaves as well as the flashiness of its flowers.

    History and curiosities: 

    The scientific name, Grevillea robusta, consists of the genus name Grevillea, dedicated to the British botanist Charles Greville (1749-1809), and the Latin term robusta, “robust, vigorous”.

    The treen can cause contact dermatitis.
