Seedling
2-3 weeksTiny seedlings with two rounded cotyledons emerge. First true leaves are small and narrow.
Keep soil barely moist but not wet. Provide 12-16 hours of light daily under grow lights. Maintain warmth (65-70°F). Thin seedlings to prevent damping-off.
Vegetative Growth
4-8 weeks from seedlingPlant develops bushy foliage with multiple stems. Leaves become increasingly aromatic and gray-green in color.
Once established, reduce watering frequency. Pinch growing tips to encourage branching. Begin light harvesting once plant has 6+ stems. Feed sparingly with balanced or low-nitrogen fertilizer if needed.
Flowering
4-6 weeks (late spring to early summer)Small pink, purple, white, or lavender flowers appear in terminal spikes above the foliage. Bees and butterflies visit frequently.
Flowers are edible and attract beneficial insects. Deadhead spent flowers to promote continued leaf production, or allow flowering to continue for ornamental and wildlife value. Water regularly but allow soil to dry between waterings.
Maturity & Maintenance
Year 2 onwardEstablished plant forms a compact, woody mound (8-12 inches tall). Foliage remains evergreen in most climates.
Prune after flowering or in early spring to maintain shape and vigor. Remove any winter-damaged branches in spring. Do not heavily prune in fall as this weakens winter hardiness. Mulch lightly in zone 4 for winter protection.
Winter Dormancy
3-4 monthsIn cold zones, foliage may darken or turn slightly bronze. In mild zones, plant remains actively green.
Reduce watering significantly. Provide protection (frost cloth, mulch) in zone 4. Avoid fertilizing. Plant can still be harvested sparingly on mild days for fresh leaves.

Harvest leaves anytime once plant is established (6+ weeks from transplant). Pinch 1-2 inches from stem tips to encourage bushiness. Best flavor before flowering, but flowers are also edible.
