@shutterbug49 No, it is from the chicory family like the endive. The outer green leaves would be a bit bitter, that is why we mainly eat the white ones in the core. It is dense and crisp like the iceberg lettuce. A big advantage is that you can preserve it very long throughout the winter and the spring, even after harvest. This vegetable is very easy to grow : just seed it, and it will take care of itself.
