Seed germination
2-4 weeksTiny seedlings emerge with cotyledons and first true leaves
Keep soil moist but not wet; provide cool conditions (50-60°F); seedlings are slow to establish
Rosette formation
4-8 weeksYoung plants develop tight, compact rosettes of narrow, spoon-shaped leaves
Maintain consistent moisture; provide excellent drainage; avoid overhead watering to prevent crown rot
Vegetative growth
8-12 weeks or longerRosettes expand and thicken; plant develops into a mound of attractive foliage
Continue good drainage practices; grit top-dressing helps prevent crown rot; minimal fertilizer needed
Flowering
3-6 weeks (spring)Delicate flower stems emerge from rosette centers bearing clusters of small 5-petaled flowers in pink, red, or white
Provide adequate light for best blooms; remove spent flowers to encourage more blooms; maintain consistent watering
Post-flowering dormancy
6-9 monthsPlant rests over summer and fall; foliage remains attractive year-round as evergreen
Reduce watering; ensure excellent winter drainage; protect from heavy, wet snow
