Superb Grevillea

Grevillea x hybrida 'Superb'

The Story

Plant Bio

Grevillea is a genus of evergreen Australian shrubs and trees in the Proteaceae family, characterized by highly specialized, petal-less flowers and a high sensitivity to soil phosphorus. These plants rely on specialized cluster roots to absorb nutrients in extremely nutrient-poor soils, making standard fertilizers toxic to them.

'Superb' is a garden-bred hybrid selection that forms a sprawling, wide-spreading shrub with deeply divided, fern-like green foliage. It produces large, curved, toothbrush-like flower clusters of apricot-pink and reddish-orange intermittently throughout the year, with peak display from late winter through spring.

Uses & Benefits:

Produces striking, apricot-pink and orange toothbrush-like flower clusters over a long season against deeply divided, fern-like foliage.

Serves as an effective, drought-tolerant barrier or screen in warm, coastal, or dry landscapes.

Provides a high-energy nectar source for hummingbirds and bees throughout the year.

Planting

How to Grow

Select a site with full sun and exceptional, sharp drainage, such as a raised bed or sandy slope.
Dig a hole twice as wide as the rootball but no deeper, ensuring the crown sits slightly above the soil line.
Backfill with native soil without adding organic compost or fertilizer, as these can hold too much moisture and nutrients.
Water deeply to settle the soil, then apply a shallow layer of coarse, open-textured mulch, keeping it clear of the main stem.

Pro Tip

Prune only the soft, green outer growth immediately after a flowering flush; cutting back into old, leafless wood prevents new shoots from forming.

Keep It Thriving

Care Guide

Do

Water regularly during the first two growing seasons to establish a deep root system.
Use only specialized low-phosphorus or native-formulated fertilizers if feeding is necessary.
Wear gloves when handling the plant to avoid contact dermatitis from the sharp, lobed leaves.

Don't

Do not apply standard high-phosphorus fertilizers, which cause severe leaf burn and plant death.
Do not plant in heavy, poorly draining clay soils that retain water.
Do not prune hard into old wood that lacks active green leaves or nodes.

Common Questions

Superb Grevillea questions

What zones can Superb Grevillea grow in?

Superb Grevillea is hardy in USDA Zones 9–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

Is Superb Grevillea deer resistant?

Not reliably. Deer may browse Superb Grevillea, especially tender spring growth — plan on repellents or fencing where pressure is high.

When does Superb Grevillea bloom?

Superb Grevillea typically blooms in late winter through year round. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Superb Grevillea need full sun?

Superb Grevillea does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Superb Grevillea drought tolerant?

Yes — once established (usually after the first full season), Superb Grevillea handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
