3-4 weeks

Tiny rosettes of fine, needle-like green foliage emerge; growth is slow initially

Keep soil consistently moist but not waterlogged; provide bright light; thin seedlings to proper spacing

Vegetative Growth

4-8 weeks

Dense, compact cushion of fine grass-like leaves develops; plant remains low to ground

Reduce watering frequency; ensure excellent drainage; no fertilizer needed; weed carefully around young plants

Flowering

4-6 weeks

Delicate white, papery flower heads on thin stems rise above the foliage; blooms appear in early to mid-spring

Deadhead spent flowers to encourage continued blooming; water moderately during bloom period; stake if needed in windy locations

Seed Development

2-3 weeks

Flower heads dry and seed capsules form; foliage remains evergreen throughout season

Allow some flowers to remain for self-seeding or seed collection; reduce watering to minimal
