Seed Germination
2-4 weeksSeeds are tiny and require light to germinate; they develop a small rosette of hairy leaves.
Surface sow on moist, gritty soil. Provide cool stratification (4-6 weeks cold period). Keep soil moist but not waterlogged. Germination is slow and irregular, taking 2-4 weeks.
Seedling & Rosette Development
3-6 monthsSmall rosettes of hairy, textured leaves emerge and gradually expand. Plant remains compact and low-growing.
Maintain gritty, well-draining soil. Provide bright light but avoid direct afternoon heat. Water carefully to avoid damping off. Handle delicate seedlings with care.
Vegetative Growth
6-12 monthsThe rosette enlarges with more hairy leaves developing. The plant forms a tight, dense mound, typically 2-4 inches tall.
Ensure excellent drainage around the plant. Apply gravel or grit mulch to prevent moisture accumulation around leaves. Protect from excessive humidity and wet conditions.
Flowering
4-8 weeksSmall flower stalks emerge from the rosette center, bearing delicate pink to magenta flowers with reddish, hairy calyces. Flowers typically appear in late spring to early summer.
Maintain consistent moisture during flowering without waterlogging. Deadhead spent flowers to encourage continued blooming. Provide cool conditions and good air circulation.
Seed Set & Dormancy
8-10 weeksAfter flowering, the plant produces small seed capsules. As temperatures drop in fall, foliage may die back partially or fully depending on zone.
Allow seeds to mature if collecting. Reduce watering as plant enters dormancy. Provide winter protection in colder zones with a gritty, well-draining mulch layer to prevent frost heave.
