Origin of Chinese cabbage
Gynostemma pentaphyllum grows freely, initially in colloidal spherical shape, then in flaky shape, up to 10 cm, brown or dark olive, and black or dark brown after drying.
The groundsel only likes the soil rich in calcium, and can grow rapidly in the dark and humid environment. There are a lot of cultivated groundsel in Gansu, Qinghai, Ningxia, Inner Mongolia and other places in China. The price of fresh groundsel is about ten yuan a catty, and the price of dried groundsel is 100 yuan a catty, which varies according to region, quality, type and price.

Growth characteristics of Physalis alkekengi
It has strong vitality and adaptability to temperature. It can survive and multiply from cold Antarctica to hot desert, from snow-capped mountains over 5,000 meters to places where volcanoes erupt. It has strong drought tolerance and wide adaptability to soil, and it can thrive even in places where grass does not grow.
Growth environment of Chinese cabbage
Wild ground vegetables can be dug up all year round, but the ground vegetables after heavy rain in spring and autumn are the freshest and more delicious, because the temperature at this time is between 20 and 28 degrees, and there is enough rain and high air humidity, which is very suitable for the growth of ground vegetables.
Ground vegetables are sensitive to pollution, especially to the concentration of sulfur dioxide in the air. Higher concentration will lead to the death of ground vegetables, so it is often difficult to find ground vegetables near cities.
