Plant Needs
Sunlight
Requires at least 6 hours of direct sunlight daily for abundant flowering; tolerate partial shade in hot summer climates to prevent leaf scorch
Watering
Water deeply when the top 5–7 cm of soil is dry; avoid overwatering to prevent root rot, especially in heavy clay soils
Temperature
Cold-hardy to -20°C; thrives in cool to temperate conditions; protect from prolonged heat above 30°C to avoid stress

Care Guide
Watering
Keep soil consistently moist during active growth and bloom period; avoid waterlogging
Fertilization
Apply a balanced slow-release fertilizer in early spring before new growth emerges. Avoid high-nitrogen fertilizers which may promote foliage over blooms
Eggshell powder topdressing：Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of plants in early spring; avoid direct contact with stems to prevent rotPruning
- Deadhead spent blooms promptly after flowering to redirect energy to root and foliage growth
- Cut back all dead foliage to ground level in late autumn to eliminate overwintering disease pathogens
- Thin crowded clumps every 3–4 years in early spring to improve airflow and encourage larger blooms
- Stake tall stems in early spring before flower buds develop to prevent breakage under bloom weight
