Chinese cabbages are a group of popular, temperate leafy vegetables belong to the same family as cabbage, broccoli, and cauliflower, i.e. mustard family, also known as Cruciferae family or Brassicaceae family. Chinese cabbages are biennial in their growing habit but are grown as annuals for vegetable purposes. In case of biennial plants, vegetative growth phase is completed during the first year of growing while reproductive phase is completed during the second year. Since vegetative parts of the plants are used for vegetable purposes in case of cruciferous vegetables, these crops are normally grown as annuals.
