The leaves are grayish green and similar to those of the olive tree. The curious and attractive spider-like flowers can be red, orange or yellow. They bloom from winter to spring. They are used as isolated specimens, to form hedges and windbreaks, on dry and sunny slopes and in shrubby groups. They are ideal for Mediterranean coastal gardens due to their resistance to wind. They attract butterflies and bees. The Grevillea olivacea needs full sun exposure and a Mediterranean climate. They resist light and occasional frosts. They grow in any type of soil that has excellent drainage. Planting is done in the fall. They are very resistant to drought plants that need moderate watering, waiting for the substrate to dry completely. Fertilize with a little compost in the fall. Prune after flowering, slightly shortening the buds that have flowered. They are plants resistant to the usual pests and diseases but sensitive to the accumulation of water in the roots. They are propagated from seeds sown in spring or autumn in the nursery and by semi-woody cuttings. |
