Collards is a biennial where winter frost occurs, and perennial in even colder regions. The plant (also known as tree-cabbage or non-heading cabbage) is a cool-season vegetable green that is rich in vitamins and minerals. It grows better in warm weather and can tolerate more cold weather in late autumn than any other member of the cabbage family. Although collards is a popular substitute for cabbage in Southern Europe yet it can also be grown in northern areas because it is frost-tolerant.
