Seedling
2-3 weeksTiny oval leaves emerge in a rosette pattern; very fine, delicate foliage visible after 7-14 days.
Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to prevent crowding.
Vegetative Growth
4-6 weeksPlant develops low basal rosette of oblong, textured green leaves with visible veining; stolons or rhizomes may begin spreading.
Water moderately; allow soil to dry slightly between waterings. No fertilizer needed; avoid overfeeding.
Flowering
8-12 weeks (mid-spring through fall, with peak in summer)Upright square stems emerge with dense purple-violet tubular flowers in tight spikes (4-6 inches tall). Multiple flower spikes may develop on mature plants.
Deadhead spent flowers to encourage continuous blooming and prevent excessive self-seeding, or leave flowers for seed production.
Seed Production & Dispersal
6-8 weeks (late summer through fall)Flowers dry and develop small seeds in the calyx; seed heads persist on stems. Seeds self-sow readily or can be collected.
Allow some flowers to remain for seed if propagation desired. Collect seed heads before they shatter. Cut back after frost.
Dormancy
3-5 months (late fall through early spring)In cold climates, foliage dies back to ground; roots and rhizomes survive underground. Perennial crowns remain dormant until spring warmth.
No care needed in winter; plant is extremely cold hardy. In mild climates, may remain partially evergreen.

Harvest Tips
Harvest leaves and flowers for fresh use or drying anytime during the growing season, preferably in early morning after dew dries. Cut stems just above leaf nodes to encourage branching. For medicinal use, harvest flowering tops at peak bloom (summer) when essential oil content is highest. Dry by hanging upside-down in a warm, well-ventilated area (1-2 weeks). Leaves remain usable for herbal infusions year-round.
