Allergy information
Perilla frutescens may cause mild allergic reactions in some people, especially those sensitive to pollen or plant sap. The main triggers are its pollen and contact with its leaves or sap. Symptoms can include skin irritation or mild respiratory discomfort. To reduce exposure, avoid handling the plant if you have sensitive skin and keep it away from areas where pollen can spread indoors.
Common problems
Overwatering can cause root rot, and poor air circulation may lead to fungal diseases. Sometimes aphids or spider mites may appear but are usually easy to control.
Uses
Used as a culinary herb in Asian dishes, also grown for ornamental purposes and sometimes for medicinal uses.
Notes
Pinching back the tips encourages bushier growth. It can self-seed easily, so deadhead flowers if you want to control spreading. Repot annually if grown indoors.
