Red Cabbage

The red cabbage leaves are coloured dark mauve. However, the plant changes its colour according to the ph value of the soil. On acidic soils, the leaves grow more reddish while an alkaline soil will produce rather blue coloured cabbages. This explains the fact that the very same plant is known by different colours in various regions. Red cabbage needs well fertilized soil and sufficient humidity to grow. Red cabbage can be stored easily. This is also used as an acidic solution tester.
