Seedling
2-3 weeksTiny true leaves emerge with characteristic wrinkled texture visible from early stage; cotyledons are smooth, followed by distinctly crinkled foliage
Keep soil consistently moist but not waterlogged. Provide bright indirect light. Thin seedlings to prevent crowding. Maintain 65-75°F temperatures.
Vegetative Growth
3-4 weeksBushy plant develops multiple stems with deeply wrinkled, textured leaves; purple-tinged veins appear in foliage; plant reaches 12-18 inches tall
Pinch growing tips to encourage bushiness and prevent early flowering. Maintain moderate moisture and regular fertilization every 2-3 weeks with balanced fertilizer. Remove any flower buds if focusing on leaf production.
Pre-flowering
2-3 weeksPlant becomes fuller and more compact; flower buds begin to form at branch tips; foliage color deepens and texture becomes more pronounced
Continue pinching tips if leaf production is priority. Reduce nitrogen fertilizer to slow flowering. Water regularly and monitor for pests. Harvest leaves frequently to encourage new growth.
Flowering
4-6 weeksSmall purple or pink flowers appear in delicate spikes at stem tips; plant energy shifts toward seed production; new leaf growth may slow
Harvest leaves frequently before flowering for best flavor and tenderness. Deadhead flowers if you want to extend leaf production. Allow some flowers if you want seeds for next season.
Seed Production & Decline
Ongoing; plant declines with frostFlowers mature into small round seeds; plant becomes woody and less flavorful; foliage may yellow and drop; plant approaches end of season
Collect seeds if desired for future planting (self-seeds readily). Continue harvesting mature leaves. In frost-free areas, plant may persist; in cold zones, prepare for end of season.
Common Pests
-
Hand-pick in early morning; use row covers in vulnerable stages; apply neem oil or insecticidal soap; avoid traps near herb gardens
-
Spray with strong water jet; apply neem oil or insecticidal soap; encourage beneficial insects like ladybugs; avoid excessive nitrogen fertilizer
-
Increase humidity by misting; spray with neem oil; remove heavily infested leaves; ensure adequate watering
-
Use yellow sticky traps; spray undersides of leaves with insecticidal soap; apply neem oil; improve air circulation
-
and
Hand-pick, especially at night; use copper barriers; apply diatomaceous earth; eliminate hiding places

Harvest Tips
Begin harvesting leaves when plant is 6-8 inches tall, pinching top leaves to encourage bushiness. Harvest frequently for tender, flavorful leaves—older, mature leaves become tougher and more bitter. Best flavor is just before flowering. In Japanese cuisine, young leaves are preferred. Harvest in early morning after dew dries for best flavor and shelf life. Cut individual leaves or stems just above leaf nodes to encourage branching.
Fun Facts
- 🌱 Chirimen-Shiso's name comes from 'chirimen' (crinkled linen fabric) because the extremely wrinkled leaves resemble the texture of traditional Japanese crinkled textiles.
- 🌱 In Japan, red perilla (akashiso) varieties are commonly used to dye and flavor pickled plums (umeboshi), while Chirimen-Shiso's green form is preferred fresh for its milder flavor and ornamental appeal.
- 🌱 Perilla self-seeds readily and has become naturalized in parts of North America and Europe; some regions consider it invasive, so deadhead flowers if you want to prevent volunteer seedlings.
