Seedling
2-3 weeksSmall plants with 2-4 true leaves emerging from cotyledons; initial leaves are smoother and less wrinkled than mature foliage
Keep soil moist; provide bright light to prevent legginess; thin seedlings to proper spacing if direct seeding; protect from cold drafts if indoors
Vegetative Growth
3-4 weeksRapid leaf expansion with characteristic deeply wrinkled, burgundy-tinged foliage developing; plant reaches 6-12 inches tall with multiple branch formation
Pinch growing tips to encourage bushier growth; provide consistent moisture and nutrients; maintain full sun exposure; no fertilizer needed if soil is adequately prepared
Leaf Production Peak
4-6 weeksPlant is 12-24 inches tall with abundant, fully mature wrinkled leaves at maximum flavor concentration; plant becomes dense and full
Begin regular harvesting to encourage continued leaf production; water consistently; pinch any flower buds that appear if focusing on leaf quality over seed production
Flowering
2-3 weeksSmall, pale purple or white flowers emerge on terminal spikes; leaf production begins to slow as plant diverts energy to reproduction
Remove flower buds to extend leaf harvesting period; if allowing flowers for seed, reduce watering slightly; flowers are edible and aromatic
Seed Production & End of Season
3-4 weeks until frostSeeds develop in small, four-chambered capsules; plant begins to decline as temperatures cool or frost approaches; foliage may yellow
Allow flowers to mature if collecting seeds; seeds will self-sow in warm climates; remove plant before hard freeze in cooler zones; harvest seeds when brown and dry

Harvest Tips
Begin harvesting leaves when plant reaches 6-8 inches tall, removing upper leaves and stems for continuous growth. Pinch off the top 2-3 inches of growth regularly to encourage bushy growth. Best flavor is in young to mid-age leaves before flowering; older leaves become tougher. Harvest in the morning after dew dries for best aroma and flavor. For Korean ssam (wraps), select tender, intact leaves 3-4 inches long. Can be harvested continuously until frost; in warm climates, may continue through mild winters.
Fun Facts
- 🌱 Kkaennip is the Korean name for Perilla frutescens var. crispa; in Japan it's called 'shiso' and is equally important in Japanese cuisine, particularly for sushi and tempura
- 🌱 The plant has been used in East Asian cuisine and medicine for over 2,000 years and is mentioned in traditional herbals dating back to ancient China
- 🌱 Kkaennip self-seeds readily and can become naturalized in warm climates; it is considered invasive in some parts of North America and Europe, so deadhead spent flowers in regions where it may spread uncontrollably
