Plant Needs
Sunlight
Requires full sun exposure; tolerates intense coastal sunlight and reflected heat from rocky or sandy surfaces.
Watering
Highly drought-tolerant; water only during prolonged dry spells, and avoid standing water to prevent root rot.
Temperature
Hardy to mild frosts down to -5°C; withstands high summer temperatures in arid coastal climates.
Characteristics
- Leaf: Narrow, cylindrical, silver-green succulent leaves covered in fine, fuzzy hairs to reduce water loss.

- Stem: Woody, branching silvery-gray stems forming a tangled, bushy growth habit.
Care Guide
Watering
Water sparingly every 2–3 weeks if no natural rainfall
Fertilization
No regular fertilization required. Excess fertilization can cause leggy growth and reduce salt tolerance.
Composted coffee grounds：Mix fully composted coffee grounds into the top 5 cm of soil once every two months to support slow, steady growth without over-fertilizing.Pruning
- Remove dead or damaged woody stems in early spring to maintain a tidy, bushy shape.
- Thin overcrowded branches to improve airflow and reduce pest risk.
- Trim back leggy growth immediately after flowering to encourage denser new foliage.
