Germination & Seedling
2-4 weeksTiny seedlings emerge with cotyledons and first true leaves appearing within 2-3 weeks. Initial growth is slow.
Keep soil lightly moist until established. Provide good light. Avoid damping off by ensuring good air circulation.
Rosette Formation
4-8 weeksPlant develops characteristic basal rosette of fuzzy, hairy leaves (giving it the 'mouseear' name). Leaves are gray-green and densely pubescent.
Thin seedlings to proper spacing. Reduce watering frequency; allow soil to dry between waterings. Minimal fertilization needed.
Vegetative Growth
6-12 weeksPlant expands rosette and sends out stolons (runners) that root and form new plantlets. Dense, low mound-forming growth.
Allow runners to spread or control for tidiness. Very drought-tolerant at this stage. No fertilizer needed.
Flowering
4-8 weeksThin flowering stems emerge from rosette bearing clusters of small yellow flowers (similar to dandelion blooms). Flowers attract pollinators.
Deadhead spent flowers to encourage continued blooming or allow to set seed for propagation. Minimal water needed.
Seed Production & Dormancy
Varies seasonallyFlowers transition to fluffy seed heads. Plant may go dormant in winter or continue growth depending on climate.
Allow seeds to mature for self-sowing or collect for propagation. Minimal maintenance required.

Harvest Tips
Harvest aerial parts (stems and leaves) in early morning after dew dries, ideally during or just after flowering when medicinal compounds peak. Cut or pinch stems 2-3 inches above ground. Plant regenerates quickly from roots. Dry harvested material for tea or herbal preparations. For seeds, collect when seed heads are fluffy and dry.
