Wallangarra White Gum

The Story

Plant Bio

Eucalyptus scoparia, the Wallangarra white gum, is an evergreen tree native to rocky granite peaks on the border of New South Wales and Queensland, characterized by its smooth, powdery white bark and graceful weeping habit. The narrow, glossy green foliage hangs pendulously from an open, spreading crown, emitting a characteristic eucalyptus aroma when crushed.

This species is distinguished by its exceptionally white trunk, which sheds its bark in narrow strips to reveal a fresh, powdery surface. In late spring and summer, it produces small, white to cream flowers grouped in clusters of seven along the branches.

Uses & Benefits:

Features a striking, powdery white trunk and a graceful, weeping canopy that provides year-round architectural interest.

Highly drought-tolerant once established, making it an excellent choice for windbreaks and low-maintenance xeriscaping.

Provides canopy cover and nesting sites for local wildlife, while the summer blossoms support generalist insect pollinators.

Planting

How to Grow

Select a planting site in full sun with excellent soil drainage, avoiding low-lying areas prone to standing water.
Dig a hole twice as wide as the root ball but no deeper, ensuring the soil flare sits level with or slightly above the surrounding ground.
Backfill with native soil without adding organic amendments or high-phosphorus fertilizers.
Water deeply immediately after planting to settle the soil, and maintain regular deep watering only until the root system is established.

Pro Tip

Avoid planting near structures to accommodate the mature canopy spread, and withhold heavy fertilizers to prevent weak, wind-prone growth.

Keep It Thriving

Care Guide

Do

Plant in highly draining, sandy, or gravelly soils.
Water deeply during the first active growing season to encourage deep rooting.
Prune young trees early to establish a strong central leader if desired.

Don't

Do not plant in waterlogged or poorly drained clay soils.
Do not apply heavy nitrogen or high-phosphorus fertilizers.
Do not prune heavily into old, leafless wood, as the tree will fail to reshoot.
