Red cabbage

Cabbage cultivar

The red cabbage is a kind of cabbage, also known as Blaukraut after preparation. Its leaves are coloured dark red/purple. However, the plant changes its colour according to the pH value of the soil due to a pigment belonging to anthocyanins. In acidic soils, the leaves grow more reddish; in neutral soils, they will grow more purple, while an alkaline soil will produce rather greenish-yellow coloured cabbages. This explains the fact that the same plant is known by different colours in various regions. It can be found in all of Europe, throughout the Americas, in China, and especially in Africa.
