Seedling
2-3 weeksTiny plants with 2-4 true leaves; pale green initially, developing purple tints as they grow stronger
Keep soil warm (70-75°F) and consistently moist. Provide bright light to prevent leggy growth. Thin seedlings to proper spacing once they develop true leaves.
Vegetative Growth
3-4 weeksPlant develops bushy form with deeply wrinkled, aromatic leaves; foliage becomes darker green with purple undertones
Pinch off growing tips when plant reaches 6 inches tall to encourage bushiness. Water regularly and maintain consistent moisture. Apply balanced fertilizer every 2-3 weeks.
Flowering
Starts week 5-6Small pale purple, pink, or white flowers appear in terminal spikes at branch tips; foliage may become slightly coarser
Pinch off flower buds to extend leaf production and prevent flowering, which can reduce leaf quality. If flowers are desired for ornament, allow some to bloom.
Maturity
Ongoing through seasonFull-sized bushy plant, 18-24 inches tall, with abundant harvestable wrinkled leaves and established purple coloration
Continue regular harvesting to promote continued leaf production. Monitor for pests. Reduce watering slightly as plant matures if temperatures cool.
Seed Production
6-8 weeks after floweringIf flowers are allowed to mature, small round seeds develop in papery capsules; plant becomes woody
Allow a few flowers to remain unharvested if seed collection is desired. Seeds are viable and can self-sow. Plant will decline in leaf quality after heavy seed set.

Harvest Tips
Begin harvesting outer leaves once plant reaches 6-8 inches tall, typically 4-5 weeks after planting. Pinch off individual leaves from the outside inward, or cut stems just above a leaf node. Harvest in the morning when flavor is strongest. Regular harvesting encourages bushier growth and delays flowering. Leaves are best used fresh but can be frozen or dried. Avoid harvesting more than 1/3 of the plant at once to maintain vigor.
Fun Facts
- 🌱 Ena-jiso is actually a variety of beefsteak plant (Perilla frutescens), and the deeply wrinkled leaves resemble the texture of beef muscle tissue, which is how the common name originated.
- 🌱 In Japan, perilla leaves have been cultivated for over 1,000 years and are considered essential to Japanese cuisine; the name 'jiso' comes from the Japanese term for this herb.
- 🌱 The plant is sometimes considered invasive in North America because it readily self-seeds, so harvesting or removing spent plants is recommended to prevent unwanted spread.
