Seed Germination
2-4 weeksTiny seeds germinate on moist surface; seedlings appear as microscopic green specks
Provide light, cool temperatures (60-65°F), high humidity under misting. Germination erratic and slow (2-4 weeks). Avoid damping off with excellent air circulation.
Seedling & Establishment
4-8 weeksFirst true leaves appear; tiny rosette formation begins. Plant remains diminutive with needle-like foliage
Maintain careful moisture balance—never waterlogged but not bone dry. Reduce humidity gradually. Transplant into gritty seedling mix only when several true leaves appear.
Rosette Formation
6-12 monthsDense cushion of narrow, gray-green leaves develops. Plant grows slowly, forming a tight mound
Ensure maximum drainage and sunlight. Water minimally. Mulch lightly with fine gravel around (not over) the plant to improve drainage and reduce slug access.
Flowering
3-4 weeksSmall bright yellow flowers appear in spring on tiny inflorescences above the cushion. Individual flowers are 4-petaled, clustered
Continue minimal watering. Avoid fertilizer which promotes soft growth. Deadhead spent flowers to encourage continued blooming and seed set.
Seed Production & Dormancy
4-6 weeks, then dormantAfter flowering, small silicles (seed pods) develop and ripen. Plant gradually slows growth, enters summer dormancy in hot climates
Allow seeds to mature and self-sow if desired. Reduce watering further. Provide afternoon shade in very hot regions to prevent stress.
