Growth Stages
Seedling
3-4 weeksTiny cotyledons emerge 7-14 days after planting. True leaves develop slowly with characteristic oval shape and fine serration.
Keep soil moist but not soggy. Provide bright indirect light. Thin seedlings to 2-3 inches apart.
Vegetative Growth
4-6 weeksPlant develops multiple stems and increasingly textured foliage with pronounced lemon fragrance. Bushy mounding shape forms.
Pinch back growing tips to encourage bushiness. Water regularly. Fertilize biweekly with balanced fertilizer.
Flowering
6-8 weeksDelicate whorls of small white, pink, or lavender flowers appear at stem tips and nodes throughout the plant.
Deadhead spent flowers to encourage continued growth and prevent excessive self-seeding. Harvest leaves before heavy flowering for best flavor.
Seed Production
4-5 weeksIf flowers are not deadheaded, they transition to seed development. Small, dark seeds form in receptacles.
Allow some flowers to mature if you want self-seeding next season. Collect seeds before they drop naturally.
Dormancy/Perennial Rest
3-4 monthsIn fall and winter, foliage dies back. Plant persists as underground roots and basal buds.
Cut back dead growth in late fall or early spring. Mulch in zones 3-4 for winter protection. Plant will regrow from roots in spring.
