Plant Needs
Sunlight
Full sun to partial shade; tolerates intense heat and arid conditions, with full sun promoting optimal blooming.
Watering
Water deeply but infrequently; allow soil to dry completely between waterings to prevent root rot in poorly drained substrates.
Temperature
Thrives in warm tropical to subtropical temperatures; frost-sensitive, so protect from temperatures below 10°C.
Characteristics
- Leaf: Thick, leathery, oval to oblong leaves with waxy, pale green upper surfaces.
- Flower: Clusters of star-shaped, creamy white to lavender blooms with a crown-like central structure.
- Stem/Bark: Grayish-green, fleshy stems that exude milky sap when damaged.
Care Guide
Watering
Keep soil slightly moist during active growth; avoid overwatering to prevent root rot
Fertilization
Diluted balanced liquid feed once every 2 months. Avoid over-fertilization, as excessive nutrients can reduce blooming and weaken stem structure.
Eggshell powder topdressing：Sprinkle a thin layer of finely crushed, dried eggshells on the soil surface to boost calcium levels; avoid direct contact with stems to prevent fungal growth.Pruning
- Remove dead or damaged branches in early spring to maintain airflow and shape.
- Trim back overgrown stems to encourage bushier growth and increase blooming potential.
- Cut spent flower clusters to promote continuous blooming throughout the growing season.
