Purple broccoli is very similar to regular broccoli except its florets have a purplish color to them and the heads of purple broccoli are typically smaller. Its taste is the same as regular broccoli and it can be use in the same manner. When selecting, look for thick heads of compact, tiny bud clusters that are evenly colored. It should have a fresh aroma and a firm but tender stalk. Avoid heads that have yellowing florets, a strong odor, or open buds. Also, avoid heads that show signs of wilting of the florets or stalk. Purple broccoli is not as readily available as regular broccoli.
