Grevillea 'Red Hooks' is a vigorous evergreen native shrub with deeply divided, fern like leaves and bold red spider flowers held above the foliage. The hooked flower styles give the plant its name. Growth is dense and bushy from the base, so it screens well while still flowering heavily.
It grows quickly at 50 centimetres to a metre a year in full sun and well drained soil, and it copes with sandy coastal ground, inland heat and light to moderate frost once established. Temperate, warm temperate, subtropical and Mediterranean gardens all suit it. Skip phosphorus rich fertilisers.
Councils and civic projects use it for fast screening along fence lines, in road reserves and in mass plantings where colour and bird habitat both matter. In home gardens it makes an informal hedge or a large feature shrub. The speed of establishment is what most buyers are after.
Frequently Asked Questions
About Grevillea 'Red Hooks'
What is Grevillea 'Red Hooks'?
It is a hardy hybrid grevillea grown for bold red flowers and dense, deeply lobed foliage. The blooms appear over a very long season and draw honeyeaters, bees and other pollinators. It forms a broad, bushy shrub that works as a screen or a standalone feature, and it is one of the tougher grevilleas in cultivation.
How big does Red Hooks Grevillea grow?
Mature plants generally reach 2 to 3 metres tall and 2 to 4 metres wide, so allow real width when you plant. It fills out from the base and spreads sideways as much as it climbs. Pruning from a young age keeps it more upright and contained where space along a fence line is limited.
How fast does it grow?
Fast, at roughly 50 centimetres to a metre a year in good conditions. From an advanced plant you can expect a usable screen within two seasons, quicker than most native shrubs of this size. Growth slows once the plant reaches full size, and regular pruning keeps that later growth dense.
How far apart should I plant it for a screen?
For a dense informal screen, space plants 1 to 1.5 metres apart. For a tighter clipped hedge, bring that in to about 80 centimetres. Closer spacing fills faster but the plants compete, so watering and feeding matter more in the first two years. Stagger a double row if you want a solid windbreak.
Is it suitable for coastal positions?
Yes. It tolerates salt laden wind and sandy, free draining soil, which makes it a sound choice for second line coastal planting behind the frontal dune. In very exposed front row positions the foliage can burn, so give it some shelter there. Good drainage matters more to it than soil fertility.
Does it need sun or shade?
Full sun, without qualification. Flowering drops away sharply in shade and the plant opens up and becomes leggy. Six hours of direct sun a day is the minimum for a dense, heavily flowering shrub. An open position with air movement also reduces the fungal problems grevilleas pick up in still, humid corners.
How do I care for Red Hooks Grevillea?
Prune after the main flowering flush, cutting back into leafy growth rather than bare wood, and repeat lightly through the year to keep it dense. Water weekly for the first summer, then rarely. Mulch with coarse bark or gravel, and feed once a year in spring with a low phosphorus native fertiliser.
