PlantFun
Plant Needs
Sunlight
Requires full direct sunlight; tolerates coastal salt spray and strong onshore winds
Watering
Obtains moisture from natural tidal saltwater inundation; no supplemental watering needed in native habitats
Temperature
Thrives in warm tropical to subtropical temperatures; cannot survive frost or prolonged temperatures below 10°C
Characteristics
- Leaf: Thick, leathery elliptical leaves with salt-excreting glands on undersides
- Flower: Small, cream to white clustered spikes with faint sweet fragrance
- Aerial Roots: Pencil-shaped pneumatophores grow vertically from underground roots for oxygen uptake
Care Guide
Watering
Relies on natural tidal cycles; no supplemental watering required
Fertilization
No supplemental fertilization needed in natural habitats. In controlled cultivation, dilute low-nitrogen marine-based feeds may be used sparingly
Composted seaweed tea：Use fully composted seaweed, dilute 1:40 for root drench; avoid over-application to prevent nutrient buildupPruning
- Remove dead or damaged branches to preserve structural integrity
- Thin overcrowded growth to improve airflow in managed cultivation
- Avoid heavy pruning, as growth rate is slow in tidal habitats
Toxicity
Warning: this plant may be toxic.
