Germination
2-3 weeksTiny seedlings emerge with first true leaves appearing within 2-3 weeks of sowing
Keep soil barely moist but never waterlogged. Provide bright, indirect light. Use well-draining seed-starting mix.
Seedling/Young Plant
4-8 weeksDevelopment of 4-6 true leaves; silvery foliage begins to show characteristic color
Gradually acclimate to full sun. Maintain minimal moisture. Begin fertilizing lightly with low-nitrogen formula.
Vegetative Growth
6-12 monthsPlant develops branching structure with increasingly dense, silvery-gray foliage forming a rounded mound
Reduce watering frequency. Provide full sun exposure. Minimal fertilizer; prefers nutrient-poor conditions. Light pruning to shape if desired.
Flowering
3-5 monthsDelicate pink, white, or bicolored flowers appear in small clusters above the silvery foliage, typically in spring through summer
Maintain full sun and very dry conditions. Do not fertilize during flowering. Deadheading encourages continued blooms.
Seed Production/Mature
OngoingFlowers develop into seed capsules; plant reaches full size and shape, maintaining silvery foliage year-round
Maintain drought conditions. Allow seeds to mature if propagation desired. Minimal care once established.
