Seedling
3-4 weeksTiny sprouted seeds with cotyledons and first true leaves emerging; foliage begins showing slight fuzziness.
Keep soil lightly moist but not wet; provide bright light and good air circulation to prevent damping off. Thin seedlings to prevent crowding.
Vegetative Growth
4-6 weeksPlant develops multiple stems with increasingly woolly, soft gray-green leaves; no flowers present.
Water moderately as soil dries; begin light feeding with balanced fertilizer every 4-6 weeks. Pinch tips to encourage bushiness.
Flowering
4-8 weeks (typically spring)Elongated flower spikes emerge with small purple or violet flowers densely arranged; foliage remains prominent and woolly.
Maintain consistent watering without waterlogging; reduce nitrogen feeding to encourage flowers over foliage. Deadhead spent flowers to extend blooming.
Mature/Established
Ongoing for 3-5+ yearsPlant reaches full size with dense, mounded form; foliage at peak wooliness and silvery color; flowers diminish in frequency.
Water only during drought; minimal fertilizer needed. Cut back in early spring to rejuvenate. Very low maintenance once established.
Dormancy/Winter
3-4 monthsGrowth slows significantly; foliage remains but plant enters semi-dormant state; minimal flowering.
Reduce watering; provide excellent drainage to prevent winter rot. In zones 5-6, mulch lightly or protect in harsh conditions. No fertilizing needed.

Harvest Tips
Harvest leaves in early morning after dew dries for best flavor and aroma. Pinch off individual leaves or cut stem tips as needed for fresh use. Foliage is harvestable year-round in mild climates. For drying, harvest just before flowering and hang-dry in a warm, airy location. Avoid heavy harvesting in the plant's first year.
