Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds germinate in 7-14 days. Tiny seedlings emerge with delicate cotyledons and fine foliage.

Keep soil consistently moist but not waterlogged. Provide bright light. Do not cover seeds. Thin seedlings to proper spacing early to reduce transplant shock.

2

Vegetative Growth

3-4 weeks

Plants develop feathery, finely-cut foliage and establish strong root systems. Stems elongate and branches form.

Water moderately and allow soil to dry between waterings. Deadhead early flower buds if plants are young to encourage bushier growth. Provide support with stakes if needed for tall varieties.

3

Budding

1-2 weeks

Unopened flower buds form at stem tips, often enclosed in hairy sepals that fall away as flowers mature.

Maintain consistent watering but do not overwater. Avoid wetting foliage to prevent fungal disease. Support tall varieties with stakes if needed.

4

Flowering

4-6 weeks

Large, papery flowers open with 4-6 petals, displaying brilliant colors and often dark centers or stamen clusters. Blooms typically last 1-2 days per flower.

Deadhead spent flowers to encourage continued blooming. Cut flowers in early morning for longest vase life. Allow some flowers to remain for seed production if desired.

5

Seed Production & Senescence

3-4 weeks

Petals drop and seed pods develop, enlarging as seeds mature inside. Pods turn brown and papery as plants decline.

Allow pods to dry completely on the plant if collecting seeds. Harvest pods before they split open. Plants may self-seed if pods are left in place.
