Plant Needs
Sunlight
Requires full sun exposure; adapted to tolerate salt spray and windy coastal conditions.
Watering
Drought-tolerant; water only when the top 5 cm of soil is completely dry to avoid waterlogging in sandy coastal soils.
Temperature
Hardy to light frost; tolerates high coastal summer temperatures up to 30°C without heat stress.
Characteristics
- Leaf: Succulent, fleshy, oblong to spatulate leaves with shallow or absent teeth.
- Flower: Small, four-petaled pale lavender to white blooms in terminal clusters.
- Stem: Succulent, branching stems adapted to tolerate salt spray and wind.
Care Guide
Watering
Water sparingly when topsoil is fully dry; avoid overwatering to prevent root rot
Fertilization
No regular fertilization required. Coastal soils provide adequate nutrients; fertilizing may cause excessive, weak growth.
Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle lightly on the soil surface to add calcium without overfeeding the low-nutrient-adapted plant.Pruning
- Remove spent flower heads to encourage self-seeding for next year's growth.
- Trim back dead or yellowing foliage to maintain a tidy coastal planting.
- Thin overcrowded seedlings to improve airflow and reduce competition for resources.
