Grevillea x hybrida 'Honey Gem'

The Story

Plant Bio

Grevillea is a large genus of evergreen shrubs and trees native to Australia, belonging to the Proteaceae family. These plants are characterized by their petal-less flowers, which feature long, prominent styles clustered in dense, showy inflorescences.

'Honey Gem' is a fast-growing, upright hybrid cultivar that produces large, six-inch-long cylindrical racemes of golden-orange flowers with yellow-tipped styles. Its deep green, deeply divided leaves grow up to twelve inches long and feature contrasting silvery-hairy undersides.

Uses & Benefits:

Large, golden-orange cylindrical flower spikes contrast beautifully with deeply divided, fern-like foliage.

High drought tolerance and wind resistance make it an effective screen or windbreak in coastal areas.

Heavy nectar production provides a valuable food source for hummingbirds and other pollinators.

Planting

How to Grow

Select a planting site in full sun with highly drained sandy, loamy, or clay-loam soil.
Dig a hole twice as wide as the root ball, taking care not to disturb the sensitive root system during transplanting.
Water deeply to establish, then transition to infrequent watering once the root system is mature.
Apply a low-phosphorus, native-formulated fertilizer sparingly, avoiding standard garden fertilizers entirely.

Pro Tip

Prune the canopy back moderately to heavily after each major flowering flush; neglecting regular pruning causes the base to become permanently bare and woody.

Keep It Thriving

Care Guide

Do

Prune regularly after flowering to maintain a dense, bushy habit.
Use only low-phosphorus or native-specific fertilizers.
Ensure the soil drains rapidly to prevent root rot.

Don't

Do not use standard high-phosphorus fertilizers, which cause toxic build-up.
Do not allow the roots to sit in waterlogged or poorly drained soil.
Do not disturb the sensitive root system during planting or weeding.
Do not handle the foliage or bark without gloves if you have sensitive skin.

Common Questions

Honey Gem Grevillea questions

What zones can Honey Gem Grevillea grow in?

Honey Gem 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 Honey Gem Grevillea deer resistant?

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

When does Honey Gem Grevillea bloom?

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

Does Honey Gem Grevillea need full sun?

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

Is Honey Gem Grevillea drought tolerant?

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