Seedling
2-3 weeksTiny cotyledons emerge within 1-2 weeks; first true leaves develop, forming miniature rosettes
Keep soil consistently moist but not waterlogged; provide bright light; ensure good air circulation to prevent damping off
Rosette Formation
4-8 weeksPlant develops tight mats of small, hairy gray-green leaves in basal rosettes; compact, cushion-like growth habit
Reduce watering frequency; apply grit mulch around base to improve drainage and prevent collar rot; protect from excess moisture
Budding
2-4 weeksFlower buds appear on short stems above the foliage; tight clusters of buds form in late winter or early spring
Ensure good drainage; no fertilizer needed; provide excellent air circulation; protect from cold wet conditions
Flowering
4-6 weeks (spring)Abundant fragrant white or pale pink flowers (4-petaled blooms) open in dense racemes; very showy display
Deadhead spent flowers to prolong blooming; minimal watering; enjoy the fragrance; bees and pollinators visit freely
Seed Production & Dormancy
3-4 monthsLong, thin seed pods develop after flowering; foliage may yellow slightly in intense heat; plant enters summer dormancy
Allow some flowers to self-seed if desired; reduce watering; provide afternoon shade in hot climates; cut back if growth becomes leggy

Harvest Tips
Cut flower stems in early morning when buds are just opening for longest vase life. For seed collection, allow flower clusters to dry on plant, then collect seed pods before they shatter. Deadhead spent flowers regularly to encourage extended blooming and prevent excessive self-seeding.
