Plant Needs
Sunlight
Full sun exposure preferred; tolerates partial sun in excessively hot, arid regions
Watering
Drought-tolerant; water only when the top 2–3 cm of soil is completely dry to avoid root rot

- Stem: Slender, branching stems with dense woolly pubescence to reduce water loss
Care Guide
Watering
Water sparingly during active growth; allow soil to dry between waterings
Fertilization
No regular fertilization required. Low-fertility soil supports natural growth; avoid nutrient-rich amendments which may cause leggy growth
Crushed eggshell powder topdressing：Sprinkle a thin layer of finely crushed eggshells on the soil surface; no dilution needed to avoid nutrient burnPruning
- Remove spent flower heads after blooming to prevent unwanted self-seeding if desired
- Thin overcrowded seedlings in early spring to improve airflow and reduce competition
- Clear dead foliage in late autumn to minimize overwintering pest habitat
