The Story
Plant Bio
Ceratopetalum gummiferum is an evergreen Australian shrub or small pyramidal tree, reaching ten to twenty feet in cultivation, with glossy, trifoliolate leaves that emerge with bronze or pink highlights. The true creamy-white flowers are tiny and insignificant, but they are followed by calyxes that swell and turn a vibrant salmon-pink to bright red through summer and fall.
The species is highly prized for this post-flowering display, where the expanding sepals mimic a profuse crop of red blossoms. The rough, light grey bark exudes a sticky gum when cut, giving the plant its botanical name.

Planting
How to Grow
- Select a site in full sun to maximize the intensity of the red calyx coloration.
- Incorporate organic matter into sandy or loamy soil to ensure moisture retention without compromising drainage.
- Water regularly from spring through autumn, keeping the soil consistently damp but never waterlogged.
- Apply a low-phosphorus, slow-release native fertilizer in early spring to avoid root and leaf burn.
Pro Tip
Plant in sandy, highly permeable soil on a slope or raised bed; absolute drainage is critical to prevent fatal root rot, yet the roots must never dry out completely during summer.

Care Guide
Do
- Provide full sun to ensure the brightest red color on the developing calyxes.
- Prune lightly immediately after the colorful calyx display fades to maintain a dense, bushy habit.
- Water deeply during dry summer spells to prevent leaf drop and stress.
Don't
- Do not plant in heavy clay or poorly drained soils where water can pool around the roots.
- Do not use standard high-phosphorus commercial fertilizers, which can burn the sensitive root system.
- Do not cut back hard into old, leafless wood, as buds will fail to regenerate.
