Germination
1-2 weeksSeeds sprout to reveal tiny cotyledons and first true leaves; very small rosette forms
Keep soil consistently moist but not waterlogged; provide cool temperatures (55-65°F); germination may be slow
Seedling/Rosette Establishment
4-6 weeksFuzzy, mouse-ear-shaped leaves develop in a dense basal rosette; plant remains low and compact
Gradually reduce watering; provide excellent drainage; avoid fertilizing; acclimate to outdoor conditions if starting indoors
Vegetative Growth
3-4 months (or overwinter before flowering)Mat expands horizontally with increasing density of hairy foliage; stems remain low-growing and mat-forming
Minimal fertilizer needed; ensure good air circulation to prevent fungal issues; thin or divide if becoming overcrowded
Flowering
6-10 weeks (spring through early summer)Delicate white flowers (1-2 cm diameter) emerge on short stems above the foliage mat; flowers have notched petals
Deadhead spent flowers to encourage more blooms; reduce watering slightly; avoid high humidity
Seed Production & Dormancy
Variable; extends into late summer and fallFlowers fade and small capsule-type seed pods form; foliage may slow growth in hot weather or go dormant in winter
Allow some flowers to remain for seed collection if desired; reduce water in winter; plant is drought tolerant during dormancy
