The red cabbage (Brassica oleracea var. capitata f. rubra) is a sort of cabbage, also known as red kraut or blue kraut 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 (flavins). On acidic soils, the leaves grow more reddish 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. Furthermore, the juice of red cabbage can be used as a home-made pH indicator, turning red in acid and blue in basic solutions. It can be found in Northern Europe, throughout the Americas, and in China.
On cooking, red cabbage will normally turn blue. To retain the red colour it is necessary to add vinegar or acidic fruit to the pot.
Red cabbage needs well fertilized soil and sufficient humidity to grow. It is a seasonal plant which is seeded in spring and harvested in late fall. Red cabbage is a better keeper than its "white" relatives and does not need to be converted to sauerkraut to last the winter.

Famous quotes containing the words red and/or cabbage:
“Who dreamed that beauty passes like a dream?
For these red lips, with all their mournful pride,
Mournful that no new wonder may betide,
Troy passed away in one high funeral gleam,
And Usna’s children died.”
—William Butler Yeats (1865–1939)
“The sole work and deed of universal freedom is therefore death, a death too which has no inner significance or filling, for what is negated is the empty point of the absolutely free self. It is thus the coldest and meanest of all deaths, with no more significance than cutting off a head of cabbage or swallowing a mouthful of water.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
