How to Grow Guinea Flower
Hibbertia scandens
Guinea Flower is a tough, sun-loving Australian native that works as a groundcover, scrambler, or climber. Plant in well-drained soil in full sun to part shade, water in well, then let it establish — once settled it is very drought tolerant. Feed only with a low-phosphorus native fertiliser in spring. Prune after flowering to keep it tidy and bushy. Rewarded with large golden-yellow flowers over many months.
Yearly Lifecycle
Care Essentials
Spring with a low-phosphorus native plant fertiliser. Avoid high-phosphorus feeds, which are toxic to most Australian natives including Hibbertia.
Watch For
- Scale insects
- Aphids
- Phytophthora root rot in poorly drained soils
Companions
Grevillea, Callistemon (Bottlebrush), Banksia, Native grasses
Care Requirements
Light
Full sun to part shade
Thrives in full sun and produces the most flowers there. Tolerates part shade but flowering is reduced. Handles coastal exposure and reflected heat well.
Watering
Regular until established, then drought tolerant
Water regularly for the first one to two seasons while the plant establishes. Once settled, very drought tolerant — reduce watering significantly. Overwatering or waterlogged soil encourages root rot.
Fertilizing
Low-phosphorus native fertiliser in spring only
Apply a slow-release native plant fertiliser with low phosphorus in spring. High-phosphorus fertilisers are toxic to Hibbertia and should never be used.
Pruning
Trim after flowering to keep tidy
Prune lightly after the main flowering flush in spring and again in late summer to control spread. The plant tolerates hard pruning and will regenerate from the base if needed.
Spacing
1.5 m apart as groundcover; 1 m as a climber
As a spreading groundcover, allow 1.5–2 m between plants. As a climber, one plant per 1 m of trellis is sufficient. Can spread to 2 m wide or climb to 5 m.
Growing Tips
Use a native-friendly fertiliser only
High-phosphorus fertilisers are toxic to Hibbertia and most Australian natives. Use a slow-release native fertiliser with low phosphorus in spring only.
Prune to keep compact
Without pruning the plant can spread widely. A light trim after the main flush keeps it tidy and stimulates the next round of flowering.
Very drought tolerant once established
Water regularly in the first season, then reduce. Established plants need little supplemental watering except in prolonged dry spells.
