Growth habit

Perilla likes warm and humid climate, and seeds can germinate when the ground temperature is above 5℃, and the suitable germination temperature is 18-23℃. The seedlings can tolerate the low temperature of 1-2℃, and the plants grow slowly at low temperature.

It grows vigorously in summer. The suitable temperature for flowering is 22-28℃ and the relative humidity is 75%-80%. Resistant to humidity, strong waterlogging and drought, especially in the organ formation period of the product, such as too dry air, too thick and hard stems and leaves, too much fiber and poor quality.

It has wide adaptability to soil and can grow in the shade.
