Establishment
First season (spring-fall)Young plants develop a low rosette of finely divided, deeply cut foliage. Growth is gradual as the root system establishes.
Keep soil consistently moist. Avoid transplanting frequently. Mulch around plants to conserve moisture and regulate temperature.
Vegetative Growth
Winter dormancy and early spring (2-3 months before bloom)Foliage expands into dense clumps of attractive, feathery leaves. Stems begin to elongate in preparation for flowering.
Maintain consistent moisture. Remove any dead or damaged leaves. Apply balanced fertilizer in early spring.
Budding & Flowering
4-6 weeks (typically May-June in northern zones)Flower buds form at stem tips, gradually developing into distinctive creamy white, globe-shaped flowers. Blooms open progressively over several weeks.
Support tall stems if needed with stakes. Deadhead spent flowers to encourage extended blooming. Maintain consistent moisture.
Post-Bloom & Seed Development
2-3 months (July-August)Flowers fade and foliage begins to decline, especially in warmer climates. If seeds are desired, leave spent flowers to develop seed heads.
Reduce watering slightly if foliage shows decline. Allow seed heads to mature if self-seeding is desired. Clean up dead foliage.
Dormancy
November-MarchFoliage dies back completely in late fall. The plant enters winter dormancy with roots resting beneath the soil.
Cut back dead foliage in late fall or early spring. Apply mulch for winter protection in zone 3. Reduce watering.
