Seedling
3-4 weeksTiny plants with fine, hair-like foliage emerging 7-14 days after sowing. Slow initial growth; fragile and prone to damping off.
Provide bright, indirect light; maintain moderate moisture without waterlogging. Use well-draining seed-starting mix. Avoid excessive humidity.
Establishment
4-6 weeksYoung plants 2-4 inches tall with developing rosettes of narrow, silvery leaves. Root system expanding; slow top growth.
Gradually acclimate to full sun if starting indoors. Keep soil moderately moist but not soggy. Begin light fertilization with diluted balanced fertilizer.
Vegetative Growth
4-8 weeksPlant reaches 6-10 inches tall with dense, mounding form and increasing foliage density. No flowers present yet.
Provide full sun and well-draining soil. Reduce watering frequency as plant matures. Light pruning to encourage bushiness. Avoid high-nitrogen fertilizers.
Flowering
8-12 weeks (extended with deadheading)Dense spikes of small, purple-pink flowers emerge above foliage, typically 12-16 inches tall. Blooms appear throughout summer into early fall.
Continue full sun and dry conditions. Deadhead spent flowers to encourage additional blooms. Avoid overfeeding, which reduces flowering.
Dormancy & Winter
3-4 monthsIn colder zones, foliage may take on greyish or muted tones as growth slows dramatically. Plant remains evergreen in milder zones.
Reduce watering significantly. Do not fertilize. In zones 5-6, provide mulch around base (avoid mounding over crown). Prune lightly in early spring before new growth.

Harvest Tips
Cut flower spikes when 2/3 of blooms on the spike have opened, typically mid-morning after dew has dried. Use sharp scissors or pruners to cut at the base of flower stems, leaving some foliage. For dried flowers, hang bundles in a warm, dark, well-ventilated space for 2-3 weeks. Deadhead regularly throughout bloom season to extend flowering and maintain compact form.
