Growth Stages

1

Seedling

3-4 weeks

Tiny seedlings with narrow cotyledons emerge 10-14 days after planting. First true leaves are thin and silvery.

Keep soil lightly moist but not waterlogged. Provide bright light. Thin seedlings to prevent crowding. Transplant to individual containers when first true leaves appear.

2

Vegetative Growth

4-8 weeks

Plant develops compact, bushy form with increasing silvery-green foliage. No flowers yet.

Gradually acclimate to outdoor conditions if growing indoors. Pinch growing tips once or twice to encourage bushiness. Water moderately; allow drying between waterings.

3

Pre-flowering/Budding

2-3 weeks

Flower buds form at stem tips; plant reaches near full size with dense foliage mounds.

Reduce nitrogen fertilizer if used. Ensure full sun exposure. Do not overwater. Buds will emerge in tight clusters.

4

Flowering

6-8 weeks (spring to early summer); may repeat in fall with deadheading

Purple-blue flower spikes bloom profusely along stems. Plant is at peak ornamental value; highly fragrant.

Deadhead spent flowers to encourage continuous blooming. Water only during dry spells. No fertilizer needed. Harvest flowers as desired for drying or fresh use.

5

Post-flowering/Dormancy

4-6 months through fall and winter

Flowers fade and dry on stems. Foliage remains silvery and ornamental. Plant enters semi-dormant state in late summer.

Light deadheading or leave seed heads for wildlife. Reduce watering significantly. Prune lightly in late summer if needed for shape. Prepare for winter dormancy.
