Growth Stages

Seedling

2-3 weeks

Tiny feathery cotyledons emerge; delicate, thread-like true leaves develop

Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing.

Vegetative Growth

3-4 weeks

Plant develops dense, finely divided feathery foliage; low rosette forms

Water moderately as plant establishes. Begin reducing water frequency. Pinch back early growth to promote bushiness if desired.

Budding & Early Flowering

2-3 weeks

Flower stems elongate; tight clusters of buds form at stem tips

Reduce watering significantly; allow soil to dry more. Ensure full sun exposure for optimal color development.

Full Bloom & Flowering

4-8 weeks (repeating if deadheaded)

Flat-topped flower clusters fully open with numerous tiny flowers; long blooming period

Deadhead spent flowers to extend blooming. Minimal water needed. Plant is very low-maintenance.

Seed Set & Dormancy

8+ weeks into winter

Flowers fade; seed heads form and dry; foliage may persist through winter in cold zones

Allow some flowers to remain for seeds and wildlife food. Cut back in fall or early spring. Divide crowded plants.
