Germination & Seedling
2-3 weeksTiny seedlings emerge with small oval cotyledons. Very delicate appearance with minimal foliage.
Keep soil consistently moist. Protect from drying out. Provide bright, indirect light. Germination occurs in 10-14 days at 60-70°F.
Vegetative Growth
3-4 weeksPlant develops multiple stems with characteristic small oval leaves arranged oppositely. Compact, bushy growth habit.
Maintain waterlogged conditions. No pruning necessary, but pinching back growing tips encourages bushier growth. Begin regular harvesting of outer leaves.
Flowering
4-8 weeksDelicate blue, purple, or occasionally white flowers appear in small clusters along stems. Flowers are tiny and ornamental.
Flowers attract pollinators. Maintain consistent moisture. Flowering does not significantly impact leaf quality. Deadhead if you prefer to focus energy on leaf production.
Seed Production
3-4 weeksSmall seed capsules form after flowers fade. Seeds are tiny and numerous.
Allow some flowers to remain if you wish to collect seeds. Otherwise, deadhead to encourage continued leaf production. Plants self-seed readily in wet conditions.
Maturity & Harvest
Ongoing through seasonPlant reaches full size with abundant foliage ready for regular harvesting. Can be harvested continuously throughout growing season.

Harvest Tips
Begin harvesting outer leaves when plant is 4-6 inches tall, typically 4-6 weeks after planting. Pinch or cut leaves and stem tips regularly to encourage bushier growth. Harvest in the morning after dew dries for best flavor. Young leaves are most tender and flavorful. Can harvest continuously throughout the growing season. Cut no more than one-third of plant at any time. In cooler climates, productivity drops significantly in winter but plant may regrow in spring.
