Pictures of the Eranella (Perilla) plant are as follows:
The plant height is usually more than 1 meter, the stem is green or purple, square-cylindrical, with 4 blunt edges, and is covered with villous hairs. Leaves are opposite, herbaceous, broadly ovate or nearly round, 7 to 13 cm long, 4.5 to 10 cm wide, apex short or sharp, base broadly cuneate to rounded, with tear-like coarse serrations on the edges, both sides Purple or only purple below, purple-green above, sparsely pilose, and appressed pilose below. The petiole is 3 to 5 cm long.
The flowers bloom in autumn, purple-red, arranged in axillary, densely flowered, lateral racemes; the bracts are broadly oval or nearly round, about 4 mm long, with reddish-brown gland spots. Hairless; flowers are bell-shaped, straight, about 3 mm long, 10-veined, covered with villous hairs and glandular points, bilabial-shaped, with an upper lip with 3 clefts, a smaller middle cleft, and a lower lip with 2 clefts, longer than the upper lip; corolla It is 3 to 4 mm long, the crown tube is short, the throat is nearly bell-shaped, and the crown eaves are nearly bilabial.
Extended information
Perilla prefers a warm and humid climate. Seeds can germinate when the ground temperature is above 5℃, and the suitable germination temperature is 18-23℃. It can tolerate low temperatures of 1 to 2°C during the seedling stage. Plants grow slowly in lower temperatures and thrive in summer.
The suitable temperature during the flowering period is 22-28℃ and the relative humidity is 75%-80%. It is more tolerant to moisture, has strong waterlogging tolerance, and is intolerant to drought, especially during the product organ formation period. If the air is too dry, the stems and leaves will be thick, hard, fibrous, and of poor quality. It has wide adaptability to soil and can grow in shady places.
Originally produced in China, it is mainly distributed in countries such as India, Myanmar, China, Japan, North Korea, South Korea, Indonesia and Russia. There are wild species and cultivated species in North China, Central China, South China, Southwest China and Taiwan Province.
