Seedling
2-3 weeksTiny thin shoots emerge with minimal foliage; very delicate appearance
Keep soil moist but not soggy. Provide indirect light. Thin seedlings to 3 inches apart. Protect from wind.
Vegetative Growth
4-6 weeksMultiple thin, grass-like leaves develop; plant becomes established with growing root system
Water regularly, maintain consistent moisture. Begin light harvesting once plant has 6+ leaves. Apply balanced fertilizer monthly.
Flowering
3-4 weeks, typically late spring to early summerDelicate nodding stems emerge with pink, purple, or lavender clusters of small flowers
Continue regular watering. Flowers are edible and ornamental; leave some to attract pollinators. Can deadhead spent flowers to encourage leaf growth.
Summer Growth
8-10 weeksPlant reaches full size with abundant foliage and ongoing flower production
Harvest leaves regularly to encourage bushiness. Maintain moisture during hot weather. Divide established plants every 3-4 years.
Dormancy
4-5 monthsFoliage dies back in fall and winter; plant enters cold-hardy dormancy underground
Reduce watering significantly. No fertilizer needed. Plant will reliably return in spring. Can provide light mulch in extreme cold climates.

Harvest Tips
Begin harvesting leaves once plant is established (at least 6 leaves per plant). Pinch or cut outer leaves from the base, leaving inner growth intact. Harvest regularly to encourage bushiness and prevent flowering if foliage is the priority. Flowers are edible and add ornamental value; harvest in late spring to early summer. Cut stalks regrow from the base for continuous harvesting throughout the season.
