Bresych Gwyllt Brassica oleracea

Wild cabbage is an uncultivated species used to hybridize many cool-weather crops we grow today. It originated in western Europe, and it (along with several close relatives) has been used for hybridization for many centuries. Today the group includes kale, broccoli, cauliflower, collard greens, cabbage and kohlrabi. These crops are referred to as Cole Crops. Wild cabbage is in the mustard family (Brassicaceae). The genus name is Latin for cabbage, while the specific epithet means vegetable/herb. 

It can grow in a wide range of conditions but will perform best when located in full sun in nitrogen-rich soil with good drainage. Propagate by seed.

The foliage of wild cabbage is fleshier and thicker than others of this species allowing the foliage to store water and nutrients. It forms a loose head of large green or blue-green leaves that are edible. They can be boiled or steamed until tender. 

The seeds of the wild-type species are difficult to find, but if available, the plants would make an interesting container display.

Insects, Diseases, and Other Plant Problems:. In locations where full sun is not provided, downy mildew can form. Some pests affecting this plant include slugs, snails, aphids, and white caterpillars.

The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common Cole crop diseases and other plant problems.
