The Story
Plant Bio
Ceratopetalum gummiferum, the New South Wales Christmas bush, is an upright evergreen shrub or small tree native to the sandstone soils and coastal dunes of eastern New South Wales. The true spring-blooming white flowers are small and star-shaped, but they are quickly followed by calyxes that expand and turn a vibrant brick-red to pink throughout summer.
The trifoliolate, finely serrated foliage emerges with a distinct bronze or reddish-purple flush before maturing to a glossy dark green. When cut, the smooth bark exudes a characteristic gum, a feature that gives the species its botanical name.

Planting
How to Grow
- Select a planting site in full sun to partial shade with highly permeable, acidic to neutral sandy loam or sandstone-derived soil.
- Dig a hole twice as wide as the root ball and of equal depth, ensuring the planting position has excellent drainage to prevent root rot.
- Gently settle the plant into the hole at the same depth as it was in the container, backfill, and water in thoroughly.
- Apply a thick layer of organic mulch around the root zone, keeping it clear of the main stem to retain moisture without encouraging rot.
- Water regularly during hot summer periods to prevent the soil from drying out completely while the plant establishes.
Pro Tip
Prune the canopy back by up to one-third immediately after the summer red display fades; cutting too deep into old, leafless wood results in poor and uneven recovery.

Care Guide
Do
- Plant in a highly drained position to avoid waterlogging.
- Prune annually after the summer display to maintain a dense, compact habit.
- Provide supplemental watering during hot, dry summer spells.
- Apply a low-phosphorus native slow-release fertiliser in spring.
Don't
- Do not plant in heavy, poorly drained clay soils where water pools.
- Do not prune heavily into old, bare wood as regrowth is unreliable.
- Do not allow the root zone to dry out completely during hot weather.
- Do not use standard high-phosphorus fertilisers.
