About

Native to the rocky coasts of western Europe, it is the ancestor species of cabbages such as cabbage, cauliflower and broccoli. Very resistant to cold and salt, it prefers well-nourished and moist soils. It plays a central role in food production within the herbaceous layer.

It can be planted now — September is one of the best months.
