Seedling
2-3 weeksTiny cotyledons emerge within 7-14 days; first true leaves appear with characteristic soft texture and mild fragrance
Maintain consistent moisture but avoid waterlogging. Provide bright light. Thin seedlings to prevent crowding.
Vegetative Growth
4-8 weeksPlant develops bushy mounding form with gray-green, aromatic foliage. Stems remain herbaceous and soft.
Water moderately during dry spells. Begin hardening off transplants before planting outdoors. Pinch back growing tips to encourage bushier growth.
Flowering
8-12 weeks (can repeat if deadheaded)Delicate two-lipped flowers in shades of lavender-blue, pink, or white appear in whorled spikes above foliage. Blooms attract bees and butterflies.
Deadhead spent flowers regularly to encourage continuous blooming. Water during extended dry periods. No fertilizer needed; excess nitrogen reduces flowering.
Flowering Peak & Seed Set
4-6 weeksFlowers continue abundantly if deadheaded; if allowed to set seed, flowering slows. Mature seed pods dry on the plant.
For prolonged blooms, continue deadheading. If collecting seed, allow some flowers to mature. Cut back plants by one-third if they become leggy.

Harvest Tips
Harvest leaves and flowers throughout the growing season by pinching or cutting stems just above a leaf node. Best harvested in the morning after dew dries. For drying, cut stems when flowers are just opening and hang upside down in a cool, dark place. Cut back plants by one-third in early summer after first flush of blooms to rejuvenate and promote repeat flowering.
