Prostrate Grevillea

10 years ago, I planted 5 of these prostrate grevillea 'Poorinda Royal Mantle' cultivars along a slope to one side of my property....they have now spread along the whole area to make a lush native covering. The spread of each plant is 6 metres! The plants produce these amazing toothbrush style flowers that have red/pink styles and conspicuous yellow stigmas. Insects love the flowers.
NB: This cultivar is a hybrid between Grevillea laurifolia and Grevillea willisii.
