Seedling
3-4 weeksTiny seedlings with cotyledons appear 10-14 days after sowing. Develop first true leaves with characteristic narrow, linear shape and aromatic quality.
Keep soil lightly moist but not waterlogged. Provide bright light. Thin seedlings to 3 inches apart. Transplant to individual pots at 2-3 weeks.
Establishment
4-6 weeksYoung plants develop multiple stems and fuller foliage. Root system expands significantly. Plant reaches 6-8 inches tall.
Acclimate to outdoor conditions if starting indoors. Plant in garden after last frost. Water regularly but allow some drying between waterings. Apply balanced fertilizer every 3-4 weeks.
Vegetative Growth
4-8 weeksBushy, compact growth with dense narrow foliage. Plant reaches mature height of 1.5-2 feet. Strong aromatic scent when foliage is brushed.
Pinch back tips to encourage bushiness. Deadhead spent flowers to promote continued blooming. Reduce nitrogen fertilizer to avoid excessive leafy growth at expense of flowers.
Flowering
6-10 weeks (continuous in season)Distinctive pink flower spikes (inflorescences) appear densely along stems. Flowers attract bees, butterflies, and hummingbirds. Blooms are small, tubular, and arranged in whorls.
Harvest flowers for tea or culinary use in morning after dew dries. Deadhead regularly to extend blooming period. Provide consistent water during peak bloom.
Maturity & Seed Development
Ongoing after floweringFlowers fade to brown seed pods. Plant reaches full size. Foliage may become slightly woody at base. Semi-evergreen nature means some foliage persists in winter in milder zones.
Allow some flowers to go to seed for self-seeding or seed collection. Cut back by 1/3 in late autumn. In cold zones, apply light mulch for winter protection. Divide mature plants in spring if desired.
