The Story
Plant Bio
Grevillea is a diverse genus of evergreen Australian shrubs and trees in the Proteaceae family, highly adapted to nutrient-poor soils. The distinctive blooms consist of a tubular perianth that splits open to release a long, curving style, forming clustered inflorescences that attract nectar-feeding birds.
'Fireworks' is a compact, mound-shaped hybrid cultivar growing to just over one metre tall, featuring soft, needle-like blue-green foliage. It produces clusters of bright red and yellow spider-like flowers at the branch terminals from autumn through to late spring.

Planting
How to Grow
- Select a planting site in full sun to light shade with excellent drainage, such as a raised garden bed or sandy loam slope.
- Dig a hole twice the width of the root ball but of equal depth, ensuring the plant sits level with the surrounding soil.
- Backfill with native soil, firm down gently to remove air pockets, and water in thoroughly to settle the roots.
- Apply a coarse, organic mulch around the base, keeping it clear of the main stem to prevent collar rot.
Pro Tip
Apply only low-phosphorus native fertilisers, as standard formulations trigger severe phosphorus toxicity; never prune back into old, leafless wood where dormant buds are absent.
Keep It Thriving
Care Guide
Do
- Water regularly until established, then reduce watering to dry spells only.
- Apply a low-phosphorus native fertiliser in early spring and summer.
- Wear protective gloves when handling the foliage to prevent skin irritation.
- Tip-prune regularly after flowering to maintain a dense, compact shape.
Don't
- Never use standard general-purpose fertilisers containing high levels of phosphorus.
- Do not plant in heavy, poorly drained clay soils where water pools.
- Never prune heavily back into old, hard, leafless wood.
- Do not overwater once the root system is established.

Common Questions
Spider Flower questions
What zones can Spider Flower grow in?
Spider Flower 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.
When does Spider Flower bloom?
Spider Flower typically blooms in autumn through late spring. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Spider Flower need full sun?
Spider Flower does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Spider Flower drought tolerant?
Yes — once established (usually after the first full season), Spider Flower handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
