Cabbage ‘Ruby Ball’ is a uniform, early maturing, vigorous red cabbage producing deep red, solid and compact heads for late summer and autumn cropping. The remarkably sweet flavour and high quality makes this RHS AGM variety ideal for cooking as well as pickling. Height: 40cm (16). Spread: 60cm (24).

Companion planting: Try growing cabbages with nasturtiums to draw cabbage white butterflies away from your crop, and mint to help deter flea beetles.
