Prostrate Grevillea

Grevillea × gaudichaudii 'Gaudi Chaudi'

The Story

Plant Bio

Grevillea × gaudichaudii is a naturally occurring prostrate hybrid endemic to the higher elevations of the Blue Mountains in New South Wales. The evergreen shrub forms a dense horizontal mat of deeply lobed, oak-like leaves that emerge with bronze tones before maturing to dark green.

'Gaudi Chaudi' is a vigorous horticultural selection valued for its exceptionally dense ground-covering habit and cascading form. From spring through autumn, it produces horizontal, toothbrush-style racemes of deep burgundy-red flowers that attract nectar-feeding birds.

Uses & Benefits:

Forms a dense, cascading mat of deeply lobed, oak-like foliage with bronze new growth and burgundy toothbrush flowers.

Acts as an effective weed-suppressing ground cover and stabilises soil on slopes or retaining walls.

Provides a rich source of nectar for native honeyeaters, bees, and beneficial insects.

Planting

How to Grow

Select a planting site in full sun to partial shade with highly permeable, acidic to neutral soil.
Dig a hole twice the width of the tubestock pot but to the same depth to keep the collar clear of soil.
Gently backfill with native soil, avoiding any addition of phosphorus-rich fertilisers or organic matter.
Water in thoroughly to settle the soil and apply a coarse, low-phosphorus mulch to suppress weeds.

Pro Tip

Avoid planting in heavy, poorly drained clay or applying general-purpose fertilisers; phosphorus toxicity and root rot will quickly kill the plant.

Keep It Thriving

Care Guide

Do

Prune lightly after the main flowering cycles to maintain a dense, compact mat.
Use only specialised low-phosphorus native fertilisers if feeding is necessary.
Wear gloves and long sleeves when handling the foliage to prevent contact dermatitis.

Don't

Do not prune hard into old, bare wood as the plant lacks dormant buds to shoot back.
Do not plant in waterlogged or poorly drained soils where root rot can develop.
Do not apply standard garden fertilisers containing high phosphorus levels.

Common Questions

Prostrate Grevillea questions

What zones can Prostrate Grevillea grow in?

Prostrate Grevillea is hardy in USDA Zones 8–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.

When does Prostrate Grevillea bloom?

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

Does Prostrate Grevillea need full sun?

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

Is Prostrate Grevillea drought tolerant?

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