Coconut Ice Grevillea

Grevillea x hybrida 'Coconut Ice'

The Story

Plant Bio

Grevillea is a genus of evergreen Australian shrubs in the Proteaceae family, distinguished by highly modified, petal-less flowers arranged in dense, toothbrush-like racemes. These plants are highly adapted to nutrient-poor, acidic soils and possess specialized root systems that are exceptionally sensitive to phosphorus.

'Coconut Ice' is a dense, dome-shaped hybrid shrub that produces bicolored, soft pink and creamy-yellow flower clusters throughout the year. The deeply divided, fern-like foliage is soft green with pale undersides, forming a spreading mound up to five feet tall.

Uses & Benefits:

Provides year-round bicolored pink and cream flowers and deeply divided, fern-like evergreen foliage.

Offers high drought tolerance and good resistance to coastal winds once established.

Attracts nectar-seeking birds, hummingbirds, and insect pollinators to the garden.

Planting

How to Grow

Select a planting site in full sun with excellent drainage, such as sandy loam or a raised garden bed.
Dig a hole twice the width of the root ball but no deeper, ensuring the crown sits slightly above the surrounding soil level.
Water deeply during the establishment phase, then reduce frequency to allow the soil to dry out between waterings.
Apply a thick layer of organic mulch around the base, keeping it clear of the main stem to prevent rot.

Pro Tip

Never apply standard garden fertilizers containing phosphorus, as even low levels quickly induce terminal chlorosis and kill the plant.

Keep It Thriving

Care Guide

Do

Use only low-phosphorus or native-specific slow-release fertilizers.
Prune lightly after major flowering flushes to maintain a dense, compact form.
Wear gloves when handling the plant to avoid skin irritation from contact dermatitis.

Don't

Do not prune hard into old, leafless, brown wood, as it lacks latent buds and will not regenerate.
Do not plant in heavy clay or poorly drained soils where water pools.
Do not use general-purpose fertilizers containing more than three percent phosphorus.

Common Questions

Coconut Ice Grevillea questions

What zones can Coconut Ice Grevillea grow in?

Coconut Ice 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 Coconut Ice Grevillea deer resistant?

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

When does Coconut Ice Grevillea bloom?

Coconut Ice Grevillea typically blooms in spring through fall. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Coconut Ice Grevillea need full sun?

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

Is Coconut Ice Grevillea drought tolerant?

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