Seedling
3-4 weeksTiny plants with first true leaves developing; very slow initial growth
Keep soil moist but not waterlogged. Provide bright light. Thin seedlings to prevent crowding.
Vegetative Growth
6-8 weeksPlant develops more stems and larger, characteristic velvety gray-green leaves; bushy growth habit
Pinch back growing tips to encourage branching. Begin light harvesting to stimulate bushiness. Water when top inch of soil is dry.
Establishment
4-6 monthsPlant becomes woody at base, forms a more shrubby form; establishes deep root system
Reduce watering frequency as drought tolerance increases. Mulch lightly around base. Prune to maintain shape if desired.
Flowering
4-8 weeksTall flower spikes emerge in spring/early summer with tubular flowers in shades of purple, blue, pink, or white
Harvest leaves before heavy flowering for best flavor. Leave some flowers for pollinators and self-seeding. Deadhead if leaf production is priority.
Mature/Production
Ongoing for 4-5+ yearsFully established perennial herb producing abundant harvestable foliage year-round in mild climates
Prune in spring to remove dead wood and maintain shape. Light harvesting throughout growing season maintains vigor. Cut back by one-third in late fall/early spring.

Harvest Tips
Begin light harvesting once plant has 6-8 leaves, typically 60-90 days after planting. Pinch off individual leaves or cut 4-6 inch stem tips. Harvest in morning after dew dries for best essential oil content. Avoid harvesting more than one-third of plant at once. Peak flavor occurs just before flowering. Can be harvested year-round in mild climates; in cold regions, harvest heavily before first frost. Leaves dry exceptionally well for storage.
