Growth Stages

1

Seedling

3-4 weeks

Tiny rosette of narrow, soft, silvery-green leaves with minimal branching

Keep soil barely moist, not wet. Provide bright light. Thin seedlings to prevent damping off.

2

Vegetative

2-4 months

Bushy growth with fine, linear, aromatic leaves densely clothing branches; plant becomes compact and mounded

Water moderately and allow to dry between waterings. Pinch tips to encourage branching. Begin light feeding.

3

Pre-flowering

2-3 weeks

Branch tips begin to thicken and show green bud clusters; bracts start developing color

Reduce nitrogen to encourage flowering over foliage. Maintain good drainage. Stake if needed.

4

Flowering

6-12 weeks depending on variety and climate

Showy purple or pink flower spikes with distinctive bracts (often darker or contrasting colored); blooms typically March-June in temperate climates

Deadhead spent flowers to extend blooming. Reduce watering slightly. Continue monitoring drainage.

5

Post-flowering & Dormancy

4-6 months

Flowers fade; plant enters semi-dormant phase in summer heat; growth slows, foliage may look dull

Prune lightly after flowering to maintain shape. Cut back severely in late winter (zone 8-9) or avoid heavy pruning in warmer zones. Minimal water.

Harvest Tips

Harvest flowers just as they open for best color and fragrance, typically in morning after dew dries. Cut 6-12 inches of stem for arrangements. Dry flowers upside-down in bundles in a warm, dark, well-ventilated area for 2-3 weeks. Leaves can be harvested anytime and used fresh or dried.
