Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings emerge with narrow cotyledons and first true leaves appearing fuzzy and silvery.

Keep soil lightly moist but never waterlogged; provide bright light to prevent leggy growth. Thin seedlings to prevent damping-off.

2

Vegetative

4-8 weeks

Plant develops bushy growth with silvery-green, linear foliage forming a compact mound; no flowers yet.

Pinch tips once or twice to encourage branching and fuller shape. Gradually reduce watering. Ensure excellent drainage and full sun exposure.

3

Bud Formation

2-3 weeks

Flower buds form at stem tips; plant begins to show dense purple bud clusters.

Continue regular but light watering. Do not fertilize heavily (promotes foliage over flowers). Stop pinching to allow flowers to develop.

4

Flowering

6-8 weeks (can repeat with deadheading)

Deep purple to violet flowers open along tall spikes; plant is at peak ornamental value and fragrance.

Deadhead spent flowers to encourage continuous blooming. Harvest flowers for drying. Provide full sun and minimal water; allow some stress for best fragrance concentration.

5

Dormancy/Winter

3-4 months

Plant enters semi-dormant state; foliage remains but growth slows; older wood becomes woody.

Reduce water significantly. Light pruning after first hard frost or in early spring (remove dead/damaged growth). Do not cut into bare wood. Mulch lightly in zone 5 only.

Harvest Tips

Cut flower spikes in mid-morning after dew dries but before peak heat when fragrance oils are concentrated. Harvest just as the lower flowers begin to open for best drying quality. Dry by hanging upside-down in bundles in a warm, well-ventilated area away from direct sunlight (7-14 days). For fresh cutting arrangements, condition stems in cool water.
