Copper Glow Tea Tree

Leptospermum polygalifolium 'Copper Glow'

The Story

Plant Bio

Leptospermum polygalifolium, commonly known as tantoon, is an upright evergreen shrub native to eastern Australia that naturally inhabits coastal heathlands and sandstone outcrops. It produces small white to cream-colored flowers in the leaf axils during spring and features fine, narrow foliage on arching branches.

'Copper Glow' is distinguished by its vibrant copper to burgundy-bronze new growth that matures to dark green, providing strong foliage contrast. This cultivar maintains a loose, weeping habit that reaches up to ten feet tall and requires full sun to develop its deepest foliage coloration.

Uses & Benefits:

Ornamental UsesVibrant copper-red new growth contrasts sharply with mature dark green foliage on gracefully weeping branches.
Practical UsesHighly drought-tolerant and wind-resistant once established, making it excellent for coastal windbreaks.
Ecological BenefitsProvides nectar for generalist insect pollinators during its spring bloom period.

Planting

How to Grow

  1. Select a planting site in full sun with sandy or loamy, free-draining soil.
  2. Dig a hole twice the width of the root ball and set the plant at its original container depth.
  3. Water deeply to establish, then reduce frequency to allow the soil to dry completely between waterings.
  4. Apply a low-phosphorus fertilizer sparingly in spring to prevent weak, leggy growth.

Pro Tip

Tip-prune annually immediately after flowering to maintain a dense habit; cutting back into old, leafless wood will prevent the plant from shooting back.

Keep It Thriving

Care Guide

Do

  • Plant in full sun to maximize the copper and burgundy foliage coloration.
  • Ensure the soil drains rapidly to prevent root rot.
  • Apply a light tip-prune annually after the spring flowering period.

Don't

  • Do not prune hard into old, brown, leafless wood, as it will not regenerate.
  • Do not over-fertilize, especially with high-phosphorus formulas.
  • Do not allow the roots to sit in waterlogged or heavy, boggy soil.
