What is a plant that looks like a cabbage?

One plant that resembles a cabbage is kale, particularly the variety known as ornamental kale. It has tightly packed, ruffled leaves that can be green or purple, similar to a cabbage's appearance. Another example is the bok choy, which has a bulbous base and leafy green tops that give it a cabbage-like look. Both plants are part of the Brassica family, sharing visual similarities with cabbages.
