Growth Stages

1

Germination & Seedling

2-3 weeks

Tiny seedlings emerge with first true leaves appearing within 1-2 weeks. Growth is slow initially.

Keep soil moist but not soggy. Provide bright indirect light. Thin seedlings to prevent crowding.

2

Vegetative Growth

4-6 weeks

Plant develops low rosette of oval leaves, stems begin to spread horizontally. Foliage is dense and mat-forming.

Maintain consistent moisture. Pinch back stems to encourage bushier growth. Fertilize lightly with balanced fertilizer monthly.

3

Flowering

6-10 weeks

Delicate flowers appear on upright spikes in shades of blue, pink, or white with darker veining. Blooms are prolific.

Deadhead spent flowers to encourage continuous blooming. Provide adequate water during this energy-intensive stage.

4

Seed Set & Maturation

3-4 weeks

Flowers fade and small seed capsules form along the flower stems. Plant energy shifts to seed production.

Allow some flowers to remain for seed collection if desired. Reduce watering slightly as plant prepares for dormancy.

5

Dormancy & Overwintering

3-4 months

Foliage may die back in cold climates; perennial roots survive underground. In milder zones, plant remains evergreen.

Mulch around base in cold regions. Reduce watering significantly. Remove dead foliage in spring as new growth emerges.

Harvest Tips

Harvest aerial parts (stems and leaves) during flowering for medicinal use, typically in early to mid-summer. Cut stems just above ground level in the morning after dew dries. Dry on screens or hang bundles in a warm, well-ventilated area. For seeds, allow flower heads to fully mature and turn brown, then collect and dry further.
