Description
The plant forms firm, blue‑violet heads and is a classic winter vegetable in autumn and winter. Whether it looks more like red cabbage or blue cabbage depends on the soil, acidic soil makes it appear redder, while calcareous soil gives it a bluer hue.
Care instructions
Start seedlings in March or purchase transplants and plant them about one arm’s length apart in a nutrient‑rich, firm bed. Keep the soil evenly moist, give one feeding during the season, and protect young plants with a net against cabbage white and soil flea beetles. Harvest from August to November.

nasturtium family (Tropaeolaceae)
Nasturtium serves as a trap plant for you. Aphids and cabbage whiteflies prefer it over the brassicaceae next to it.
