Wallangarra White Gum

Eucalyptus scoparia

The Story

Plant Bio

Eucalyptus scoparia, commonly known as the Wallangarra white gum, is a medium-sized evergreen tree native to the rocky granite outcrops of the New South Wales and Queensland border. The species is characterised by its smooth, pale white to light grey bark and a graceful, upright canopy with distinctly weeping branchlets.

This species is distinguished by its narrow, glossy green adult leaves that emit a strong eucalyptus aroma when crushed and hang in elegant, pendulous screens. In autumn and winter, it produces clusters of small white flowers that attract native bees and honeyeaters.

Uses & Benefits:

Ornamental UsesFeatures a graceful weeping habit, smooth white bark, and aromatic, narrow green foliage.
Practical UsesFunctions as an effective windbreak or medium-sized shade tree on dry, rocky, or sloping sites.
Ecological BenefitsProvides nectar for native bees, beneficial insects, and honeyeaters during the autumn and winter flowering period.

Planting

How to Grow

  1. Select a planting site that receives at least six hours of direct sunlight daily and has excellent drainage.
  2. Dig a hole twice as wide as the root ball but to the same depth, ensuring the soil at the base is not compacted.
  3. Gently remove the tree from its container, settle it into the hole without disturbing the root ball, and backfill with native soil.
  4. Water thoroughly immediately after planting to settle the soil, and maintain regular deep watering during the first dry season until established.

Pro Tip

Plant in a position with sharp drainage and full sun; planting this granite-belt native in heavy, waterlogged clay or shade causes root rot and sparse, structurally weak growth.

Care Guide

Do

  • Plant in free-draining sandy loam or rocky soil to prevent root rot.
  • Monitor young foliage for yellow rust pustules during warm, humid periods.
  • Provide formative training when young to establish a strong central leader.

Don't

  • Do not plant in heavy, poorly drained clay soils or low-lying wet areas.
  • Do not prune heavily into old, bare wood as regrowth is slow and patchy.
  • Do not apply high-phosphorus general fertilisers.
