Rosette Formation
6-12 weeksPlant develops dense cushion of narrow, hairy leaves; remains low to the ground (2-4 inches tall).
Maintain gritty, well-draining conditions. Begin gradual hardening off if growing indoors. Reduce watering frequency.
Pre-flowering
2-4 weeksFlower buds begin to develop at the center of the rosette. Tiny stems emerge above foliage.
Ensure excellent drainage. Do not overwater. Provide full sun exposure. Reduce nitrogen fertilizer.
Flowering
4-8 weeks (spring/early summer)Delicate white or pale yellow flowers on short stems bloom above the cushion (typically 4-6 inches tall). Multiple flowers per plant.
Water carefully at base only. Protect from excessive rain and high humidity. Remove any dead flowers. Ensure air circulation.
Seed Development & Dormancy
