Plant Needs
Sunlight
Full sun exposure for 6–8 hours daily supports optimal blooming; tolerate partial shade in regions with extreme midday heat to prevent leaf scorch
Watering
Deep, infrequent watering to encourage deep root growth; allow the top 10–15 cm of soil to dry completely between waterings to avoid root rot
Temperature
Tolerates light frost down to 5°C; avoid prolonged exposure to temperatures below 0°C or above 38°C to prevent leaf damage
Characteristics
- Leaf: Glossy, lanceolate evergreen leaves with aromatic oil glands that release a eucalyptus-like scent when crushed
- Flower: Dense terminal corymbs of bright red, pink, or orange brush-like blooms composed of numerous stamens
- Bark: Smooth, mottled grey-brown bark that sheds in irregular patches to reveal lighter, fresh bark underneath
Care Guide
Watering
Deep water every 7–10 days during active growth; increase frequency during prolonged drought periods
Fertilization
Apply a balanced slow-release fertilizer in early spring to support blooming. Use a fertilizer with low phosphorus content to support native Australian plant nutrient preferences
Eggshell powder top-dress：Grind thoroughly dried eggshells into a fine powder; sprinkle 1 tablespoon around the base of the tree and water lightly to incorporate into soil; avoid direct contact with foliage to prevent irritationPruning
- Remove dead, diseased, or crossing branches in late winter before new growth emerges to improve tree structure
- Thin crowded inner branches to enhance air circulation and promote even blooming
- Shape young trees to establish a strong central leader and maintain a balanced canopy
