The Story
Plant Bio
Hardenbergia violacea, the purple coral pea, is an evergreen woody climber native to Australia that twines vigorously over supports or spreads as a dense groundcover. In late winter and early spring, it produces a profuse display of small, purple, pea-like flowers held in drooping clusters.
The leathery, dark green leaves are simple and lance-shaped with a distinctive net-like vein pattern. The flowers feature a characteristic bright yellow-green spot at the center of the upper petal, serving as a nectar guide for bees.

Planting
How to Grow
- Select a planting site in full sun to partial shade with highly permeable, well-draining soil.
- Dig a hole twice as wide as the root ball and of equal depth, ensuring the crown sits level with the surrounding soil.
- Provide a sturdy trellis, fence, or support structure for the twining stems to climb.
- Water deeply and regularly during the first growing season to establish a deep root system.
Pro Tip
Prune immediately after flowering in spring; cutting back late in the season removes the next year's flower buds, which develop on the previous season's growth.

Care Guide
Do
- Prune annually right after the spring bloom to maintain shape and density.
- Ensure the soil drains rapidly to prevent root rot.
- Water deeply but infrequently once the plant is established.
Don't
- Do not prune late in the summer or fall, as this removes next winter's flower buds.
- Do not cut back into old, leafless, woody stems which lack active buds to regenerate.
- Do not overwater or allow the roots to sit in soggy, waterlogged soil.

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