Seedling
2-3 weeksTiny seedlings with first true leaves emerging; plants are delicate and tender
Keep soil warm (70-75°F) and consistently moist; provide bright indirect light; thin seedlings to prevent crowding
Vegetative Growth
4-6 weeksRapid expansion of heart-shaped leaves; plant develops multiple branches and thickens; foliage becomes more fragrant
Pinch back growing tips to encourage bushier growth; maintain consistent moisture and warmth; apply balanced fertilizer every 2-3 weeks
Flowering
3-4 weeksSmall pale pink, purple, or white flowers appear in panicles at stem tips; foliage remains harvestable
Deadhead spent flowers to extend leaf production if harvesting only for leaves; flowers are also edible and aromatic
Seed Development
2-3 weeksFlowers mature into small dark brown or black seeds; plant energy shifts to seed production; leaves may become less tender
Allow flowers to remain if seeds are desired for next season; harvest leaves before seeds fully mature for best flavor
Senescence
1-2 weeks before frost killPlant begins to decline as temperatures drop or after frost exposure; foliage may yellow and wilt
Harvest all remaining leaves before hard frost; plant is frost-sensitive and typically ends in fall; save seeds if desired

Harvest Tips
Begin harvesting leaves when plant is 6-8 inches tall; pinch off the top 2-3 sets of leaves regularly to encourage bushiness and continuous production. Harvest in the morning after dew dries for best flavor. Young, tender leaves offer the most delicate flavor; older leaves develop stronger, more assertive taste. For culinary use, harvest before flowering for maximum tenderness. Can harvest continuously throughout the growing season by removing leaves from the top. If saving seeds, allow some flowers to mature fully; seeds drop naturally when ripe or can be collected by cutting seed heads and drying them.
Fun Facts
- 🌱 Egoma is called 'shiso' in Japan, where it has been cultivated for over 2,000 years and holds deep cultural significance in Japanese cuisine and traditional medicine.
- 🌱 The plant's seeds, called 'egoma' specifically in Japanese, are pressed to make egoma oil, a traditional culinary oil rich in alpha-linolenic acid (omega-3 fatty acids) and highly prized in Japanese cooking.
