Seedling
2-3 weeksTiny seed leaves emerge with fuzzy, pale purple coloring. True leaves begin showing distinctive crimped edges.
Keep soil warm (70-75°F) and consistently moist. Provide bright indirect light indoors. Thin seedlings to prevent crowding.
Vegetative Growth
4-6 weeksPlant develops multiple stems and the characteristic deeply lobed, wrinkled purple foliage darkens. Leaves reach full size with intense coloring.
Pinch growing tips to encourage bushier growth. Fertilize every 2-3 weeks with balanced fertilizer. Ensure adequate spacing and air circulation.
Mature Foliage
3-4 weeksPlant reaches full size (1-2 feet tall) with abundant dark purple, crinkled leaves. Foliage is at peak flavor and aroma.
Harvest regularly to encourage continued leaf production. Continue light fertilizing. Monitor for pests.
Flowering
2-3 weeksSmall delicate lavender or pale purple flowers appear in terminal spikes. Seeds begin to set.
You can deadhead flowers to extend leaf production, or allow flowering for seed collection. Let some flowers mature if you want self-seeding.
Seed Production
2-3 weeksFlowers fade and seed pods develop. Seeds are small and numerous in dried flower heads.
Allow seed heads to dry on plant if saving seeds. Cut heads when brown and store in cool, dry place. Seeds remain viable for 1-2 years.

Harvest Tips
Begin harvesting outer leaves when plant is 6-8 inches tall, typically 4-6 weeks after planting. Pinch off leaves regularly throughout the season to promote bushier growth and continuous production. Best harvested in morning after dew dries. For pickling (umeboshi), harvest young leaves. Flowers can be eaten as garnish and are edible. Cut entire stalks near the base for larger harvests, leaving lower growth to regenerate.
