Grevillea Knockout 140mm

Grevillea 'Knockout' is a spectacular Australian native renowned for its masses of brilliant crimson-red spider flowers that create a dazzling display for much of the year. The vibrant blooms are beautifully complemented by fine, deep green foliage, making this fast-growing shrub a standout feature in native gardens, mixed borders and informal screens. Rich in nectar, it is a favourite of honeyeaters, bees and butterflies, bringing colour, movement and wildlife into the garden.

Growing to around 2–3 metres tall and wide, Grevillea 'Knockout' thrives in full sun and well-drained soil. Tough, drought tolerant once established and easy to grow, it is perfectly suited to Australian conditions and performs exceptionally well in coastal, native and low-maintenance landscapes.

Tip: Give Grevillea 'Knockout' a light prune after flowering to maintain a dense, compact shape and encourage even more spectacular blooms. Feed with a low-phosphorus native fertiliser in spring, and avoid heavy soils or overwatering to keep your plant healthy and thriving for years to come.
