The Story
Plant Bio
Gompholobium huegelii, known as the common wedge-pea, is an erect, open Australian shrub with slender branches and a woody base. The foliage consists of narrow, bluish-green trifoliate leaves with margins that roll tightly backward.
This species is distinguished by its large, yellow pea-like flowers that are shaded with dull grey or yellowish-green on the reverse of the petals. The blooms appear singly or in small terminal clusters from spring through summer.

Planting
How to Grow
- Select a planting site with full sun to partial shade and exceptional drainage, such as a raised bed or rock garden.
- Prepare the soil using a sandy or gravelly loam mix, ensuring the pH remains acidic to neutral.
- Plant the shrub high in the soil profile to prevent water from pooling around the crown.
- Water sparingly once established, allowing the soil to dry out completely between waterings.
Pro Tip
Prune lightly immediately after flowering to maintain a dense habit; cutting back into old, leafless wood kills the stem as it lacks latent buds to regenerate.

Care Guide
Do
- Plant in highly permeable, sandy, or gravelly soils to ensure rapid drainage.
- Prune lightly immediately after the flowering season to encourage bushy growth.
- Use only low-phosphorus or specialized native fertilizers if feeding is necessary.
Don't
- Do not plant in heavy clay or waterlogged soils, which trigger rapid root rot.
- Do not prune hard into old, bare wood lacking active foliage.
- Do not apply standard garden fertilizers containing high phosphorus levels.

Common Questions
Common Wedge-pea questions
What zones can Common Wedge-pea grow in?
Common Wedge-pea 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 Common Wedge-pea deer resistant?
Not reliably. Deer may browse Common Wedge-pea, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Common Wedge-pea bloom?
Common Wedge-pea typically blooms in spring through summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Common Wedge-pea need full sun?
Common Wedge-pea does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Common Wedge-pea drought tolerant?
Yes — once established (usually after the first full season), Common Wedge-pea handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
