Seedling
4-6 weeksTiny rosettes with 2-4 true leaves; very small and fragile
Maintain high humidity under bright lights or greenhouse conditions; avoid damping off with excellent air circulation; keep soil barely moist
Rosette Development
3-6 months before floweringCompact, densely-packed silver-edged evergreen leaves forming low mounds; no flower stems yet
Establish regular watering schedule; ensure excellent drainage; place in cool location (60-65°F preferred); no fertilizer needed if soil is decent
Flowering
4-6 weeks (typically April-May in northern zones)Short flower stems (3-4 inches) emerge from leaf rosettes, each producing clusters of lavender-blue flowers with white centers; silvery foliage becomes more pronounced
Maintain consistent moisture; deadhead spent flowers to extend blooming; provide cool temperatures (below 70°F) for longest display; light liquid fertilizer monthly is optional
Post-Flowering
5-7 months (June-December)Flower stems wither; rosette remains intact and evergreen; seed pods may form if flowers are not deadheaded
Remove dead flower stems; reduce watering slightly; ensure good drainage to prevent rot during dormant period; allow plant to rest in cool conditions
Dormancy
2-3 months (December-March in cold zones)Plant enters semi-dormancy in winter; rosette persists but growth essentially stops; foliage may show silvered appearance more strongly
Water very sparingly; protect from winter wet with gritty mulch; avoid crown moisture; ensure air circulation; excellent drainage is critical
