Purple cabbage is a variety of cabbage that has an intense deep purple color as opposed to the whitish green hue of a regular cabbage. They taste slightly more bitter than the regular variety but provide more nutrition. They can be eaten stewed or raw as an addition to salads. Purple cabbages grow from seeds, which can be bought from any gardening store.
Cabbages in general are not a big fan of heat and should be planted in the shade, as they tend to bolt (producing stems and flowers instead of leaves) in the heat. Prepare the soil by de-weeding it, and add compost to make it fertile. Sow the seeds 12 to 24 inches apart from each other. Add fertilizer once a week, as cabbages require a lot of fertilizer. Water regularly to keep the soil moist but not wet. Cabbages are ready to harvest at around 2 months from the time of sowing, where cabbage heads will appear.
