Prefers full sun to partial shade; tolerates disturbed, low-fertility soils
Watering
Drought-tolerant; water only during prolonged dry periods to avoid waterlogging

Care Guide
Watering
Water sparingly when top 5 cm of soil is dry
Fertilization
No fertilization required; tolerates nutrient-poor substrates. Fertilization may encourage excessive vegetative growth and increased self-seeding
Composted coffee grounds tea：Use fully composted grounds diluted 1:40 to avoid nutrient burn; apply only if soil shows severe nutrient deficiencyPruning
- Remove spent flower heads before seed set to limit self-seeding spread
- Thin dense stands to improve airflow and reduce competition for resources
- Pull entire mature plants before flowering to control weed populations
