Purple Coral Pea

Hardenbergia violacea 'Free n Easy'

The Story

Plant Bio

Hardenbergia violacea, commonly known as purple coral pea, is a vigorous evergreen climber native to eastern and southern Australia that twines via woody stems. The species produces stiff, leathery, mid-to-light green leaves and dense clusters of pea-shaped flowers from late fall through early spring.

'Free n Easy' is distinguished by its profuse clusters of white blossoms that are softly suffused with lavender-pink or mauve. This cultivar maintains a highly vigorous, dense growth habit, making it equally effective as a climbing trellis cover or a sprawling groundcover.

Uses & Benefits:

Ornamental UsesProvides a dense, evergreen screen of glossy foliage covered in white and lavender-tinged flowers during winter.
Practical UsesFunctions as an effective groundcover for erosion control on dry, sloping sites.
Ecological BenefitsAttracts bees, butterflies, and other beneficial pollinating insects during the cooler months.

Planting

How to Grow

  1. Select a planting site with full sun to partial shade and exceptionally well-draining soil.
  2. Install a sturdy trellis, fence, or support structure before planting to guide the twining woody stems.
  3. Dig a hole twice the width of the root ball, insert the plant at its original soil level, and backfill without adding heavy organic matter.
  4. Water deeply to establish, then reduce frequency to allow the top few inches of soil to dry completely between waterings.
  5. Apply a low-phosphorus, slow-release fertilizer once in spring, avoiding standard high-phosphorus formulations.

Pro Tip

Provide a trellis structure early to prevent stems from tangling into a matted heap, and never prune in fall or winter when flower buds are already set.

Keep It Thriving

Care Guide

Do

  • Prune firmly immediately after the spring flowering season finishes to maintain shape and density.
  • Ensure the soil drains rapidly to prevent root rot.
  • Protect young plants from hard freezes below 24°F (-4.5°C).

Don't

  • Do not prune in fall or winter, as this removes the developing flower buds.
  • Do not use standard fertilizers high in phosphorus or nitrogen.
  • Do not allow the plant to sit in waterlogged or heavy clay soils.

Common Questions

Purple Coral Pea questions

What zones can Purple Coral Pea grow in?

Purple Coral Pea is hardy in USDA Zones 8–10. 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 winter through 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.
