It’s quite tasty, crisp and juicy. Use it in salads, sandwiches, steamed, boiled, or stir-fried. It’s almost a lettuce, but sturdier and tastier. It tolerates hot weather well, and grow it as you would any other cabbage. You can spring-plant, and get a wonderfully tasty and beautiful crop, but plants maturing in the quiet days of fall seem to do especially well.
Sow seeds inside under grow lights 4-5 weeks before last frost, or direct-seed after that time. Flea beetles are a common pest. Cabbageworms don’t seem to bother these plants, in my experience.
You can store them at near-freezing temperatures and high humidity in a root cellar, wrapped in newspaper. But who does that anymore? Be advised, your host here is a dinosaur.
