Mustard Family

The flowering plant family Brassicaceae, known as the mustard or cabbage family, provides much of the world's winter vegetables. These include cabbage, kale, collard, broccoli, cauliflower, brussels sprouts, chinese cabbage (bak choy, pak choy, choy sum, rapeseed (canola) and others), chinese kale, rutabaga (also known as swedish turnips or swedes), seakale, turnips, radish and kohl rabi. Other well known members of the Brassicaceae include mustard seed, horseradish and watercress.

Cabbage, broccoli, cauliflower, brussels sprouts, collards, and kale are all cultivars of one species: (Brassica oleracea)

The mustard family is found worldwide and consists of plants with annual, bi-annual and perennial life spans. Whilst some members of the Brassicaceae have seeds with a high erucic acid content, making these unsafe to eat in large doses, all members of the family are edible, although some do taste better than others. They were formerly called the Cruciferae due to the four petals of these plants looking like crosses.
