This is what you should know about the winter onion.

Winter onion is used by healers not only to strengthen health, but also finds application in digestive problems, febrile diseases and in lowering cholesterol. The winter onion belongs to the Amaryllis family (Amaryllidaceae). They are perennial plants that grow herbaceously and can reach up to one meter in height. Their minimum height of growth is thirty centimeters. The leaves of the winter bulb are hollow and round. The flowers of the plant form between June and August and have a white coloration. The bracts are shorter than the pedicels of the flowers, while the stamens protrude far beyond their sheath. A single flower is about one centimeter in size. The ripening period of the seeds of the winter onion is in July and August. Rarely, the period extends into September. The horst-forming plant develops bulbs that have a long and cylindrical shape and are white. Rarer are red colorings. Thus, the winter onion is not an edible onion in the true sense, but rather resembles leeks. The name “onion” is misleading. In the Asian region, various cultivated types of the winter onion are known. Originally, the plant comes from the Orient, where it was already cultivated about 4000 years ago. In China, on the other hand, the onion was not cultivated. This has only been the case for a few decades. In addition, winter onions also grow in wild form in Siberia. From there it came to Europe in the 17th century. In the process, it was probably transported via Russia. In England it was introduced in 1629. After the Second World War, the cultivation of the winter onion also played quite an important role in Germany. Along with the potato, it was considered one of the most important vegetables. In the meantime, the winter onion has become a cultivated plant. Today it is cultivated mainly in tropical areas. It tolerates frost and can therefore be sown as early as the previous year. In Asia, the cultivation of winter onion is usually done after rice. The optimum temperature for the plant is a maximum of 25 and a minimum of 15 degrees Celsius. Spring onions can be found throughout the year, coming from the greenhouse in autumn and winter. However, it is often the case that vegetables from the greenhouse lose some of their flavor. In addition, the plants are often more treated. Winter onions, which come into stores between April and September from outdoor cultivation, taste best. The plant owes its name, among other things, to its light onion flavor, which, however, is not as penetrating as in commercial kitchen or table onions.
