verifiedReviewed by the GreenScout Team

Red cabbage is a densely-headed brassica with deep purple-red leaves containing beneficial anthocyanins. Its color deepens with cool temperatures and acidic soil, and it has a slightly sweet, complex flavor when cooked or pickled. This variety stores exceptionally well and is more robust against many pests than green cabbage.

Frequently Asked Questions

How do I get more intense purple color on my Red Cabbage?

Its color deepens with cool temperatures and acidic soil — keeping soil pH on the lower end of the 6.0–7.5 range and growing in cooler conditions brings out the anthocyanins responsible for the deep purple-red leaves.

Is Red Cabbage more pest-resistant than green cabbage?

Yes — it's more robust against many pests than green cabbage and also stores exceptionally well, making it a reliable choice for a low-maintenance brassica bed.
