Sunlight
Dappled woodland shade; avoid direct midday sun, which can scorch delicate foliage and shorten bloom time
Watering
Keep soil consistently moist but not waterlogged during active growth; avoid drying out completely in spring
Temperature
Extremely cold-hardy; prefers cool spring temperatures and goes dormant in summer heat above 25°C
Characteristics
- Leaf: Fern-like, blue-green compound leaves with finely divided, soft-textured leaflets
- Flower: Creamy white to pale yellow heart-shaped blooms, nodding in loose, drooping racemes
- Root: Small, corn kernel-shaped tubers that store energy for dormancy
Care Guide
Watering
Maintain even soil moisture during active growth and blooming
Fertilization
Apply a diluted organic, nitrogen-light feed once at emergence. Do not over-fertilize, as this can lead to leggy growth and reduced blooming
Composted leaf mold tea：Steep fully decomposed leaf mold in water at a 1:20 ratio; drench soil lightly to add humus without burning delicate rootsPruning
- Remove spent flower stems after blooming to redirect energy to tuber development
- Cut back dying foliage completely once it yellows and wilts in late spring
- Divide tubers in early spring every 3–4 years to maintain plant vigor and prevent overcrowding
