Origin of Yuja
Yuja tree literally means the tree that fruits yuja.
It is a type of citrus, spread wide from the Yangtze Valley of China to the Tibet Valley. They are widely raised in the Jeollanamdo region in South Korea, and they can be raised indoors in the middle region. The records say they were planted, raised, and drank as tea for a long time, and the scholars argue that they were probably spread from China.
It takes a long time for a yuja tree to grow on its own, so it is usually grafted on a trifoliate orange tree. If a yuja tree is raised in a pot as an ornament, the flowers are usually cut leaving only one fruit.Seeing just one huge fruit growing for a long time does have a good vibe. It has thorns as sharp as a trifoliate orange tree so it must be handled with care.
