Native Broom

Viminaria juncea

The Story

Plant Bio

Viminaria juncea, known as native broom, is an erect, weeping evergreen shrub native to swampy regions of Australia. It features flexible, bright green, needle-like branchlets that function as leaves, giving the plant a delicate, reed-like texture.

The plant produces long, spray-like clusters of small, lemon-yellow pea flowers with orange-red centers from spring into summer. It thrives in wet, poorly drained soils where few other shrubs survive, making it highly useful for boggy garden spots.

Uses & Benefits:

Ornamental UsesOffers a unique, weeping, reed-like texture and a profuse display of yellow pea flowers.
Practical UsesThrives in waterlogged, swampy, or seasonally wet soils where other plants fail.
Ecological BenefitsProvides nectar for beneficial insects and general insect pollinators.

Planting

How to Grow

  1. Select a planting site in full sun to partial shade with moist, acidic to neutral soil.
  2. Dig a hole twice the width of the root ball and set the plant at its original container depth.
  3. Water thoroughly after planting and maintain consistent soil moisture during the first growing season.
  4. Apply a standard balanced fertilizer sparingly in spring, as this species is not sensitive to phosphorus.

Pro Tip

Prune only the young green growth to shape the canopy; cutting back into old, leafless woody stems will kill the branch.

Keep It Thriving

Care Guide

Do

  • Keep the soil consistently moist, especially during dry summer spells.
  • Prune lightly when young to encourage a dense, weeping habit.
  • Plant in poorly drained or seasonally wet areas of the garden.

Don't

  • Do not prune hard into old, bare wood, as the plant cannot regenerate from old stems.
  • Do not allow the soil to dry out completely for extended periods.
  • Do not attempt to transplant mature specimens once established.

Common Questions

Native Broom questions

What zones can Native Broom grow in?

Native Broom 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 Native Broom deer resistant?

Not reliably. Deer may browse Native Broom, especially tender spring growth — plan on repellents or fencing where pressure is high.

When does Native Broom bloom?

Native Broom 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 Native Broom need full sun?
