It forms a stout head to about 25cm (10in) high. Each head typically weighs around 2kg. The outer leaves curve inward and are dark green to pale green. The interior leaves and heart is yellow to cream coloured. It is the best storing of Chinese cabbages and can be kept several weeks when refrigerated.
