Its nature likes cold and wet climate, but not resistant to high temperature. Distributed in some high mountains in a few provinces and counties in the south of China.

Camellia other products
- Camellia can be used to refine camellia oil, which has many uses.
- 1 Used as cooking oil
- Camellia oil is a traditional edible vegetable oil unique to our country. Its production and development have a long history. According to the Shanhai Jing in the third century BC, "Member trees, oily food in the south" are also used. Camellia oleifera. [3]
- 2 for the cosmetics industry
- The research on camellia oil found that: it is rich in glycerol oleic acid, has certain stability to acidification, and is not easy to oxidize and rancid. Skin is burned by UV rays. [3]
- 3 For the preparation of biofuels
- Camellia oil contains triglycerides, and its fatty acid carbon chain is mainly C16 and C18, which is close to fossil diesel. Under the action of a catalyst, it can transesterify with methanol to produce fatty acid methyl esters (that is, first-generation biodiesel). [3]
