Cabbage - Red

Red cabbage ( botanical name Brassica oleracea or B. oleracea var. capitata F. rubra ) is a variant of white hard-heading cabbage and a descendent of three distinct cabbage types within the Brassica family. The word "cabbage" is an Anglicized form of the French caboche, meaning "head." It has been used to refer to loose-heading and nonheading forms of Brassica oleracea.

Sowing red cabbage

You can start seeds indoors (optional), so you'll need a tray, some red cabbage seeds, and starting soil. Place the tray in a sunny location such as a windowsill and make sure that the soil is always damp. Red cabbages are normally sown February to mid April for transplanting from April to early June and cropping between August and November.
