Growth Stages

Germination & Seedling

2-4 weeks

Tiny seedlings emerge with fine cotyledons; extremely delicate at this stage

Keep soil consistently moist but not waterlogged; provide bright light; maintain cool temperatures (50-60°F); use well-draining seed mix

Rosette Formation

4-8 weeks

Plant develops a basal rosette of fine, narrow, hairy leaves close to the ground

Ensure excellent drainage to prevent rot; gradually reduce watering; no fertilizer needed; maintain cool conditions

Vegetative Growth

8-16 weeks

Plant expands rosette and develops fine wiry stems; hairy foliage becomes more prominent

Water sparingly; provide full sun exposure; ensure cold winter period for proper flowering; no supplemental feeding

Flowering

4-8 weeks

Delicate white or cream daisy-like flowers with bright yellow centers bloom on wiry stems

Maintain dry conditions; support stems if needed in windy locations; deadhead spent flowers to encourage more blooms

Seed Set & Dormancy

6-12 weeks

Flowers fade to seed heads; plant enters dormancy period, especially in winter

Allow seeds to mature and dry; collect seeds if desired; reduce water; ensure excellent winter drainage
