Description
Grevillea olivacea paints a striking picture in gardens, boasting vivid red flowers from Makuru to Djilba (winter to early spring). As a large, fast-growing shrub, it not only enlivens spaces with its fiery hues but also becomes a magnet for native birds, adding a lively chorus to its visual splendour. With roots in Western Australia, this Grevillea is a proud emblem of native beauty, destined to be a garden's crowning jewel.
When sown in the ground, amending poor or sandy soils with a dedicated soil conditioner can pave the way for its optimal growth. As the plant matures, it demonstrates commendable drought resilience, though it appreciates a treat of low-phosphorus native fertiliser come Djilba (early spring). To maintain its majestic display, remember to indulge it with light, regular pruning, steering clear of heavy cuts to ensure its longevity.
