This is known by a couple names: Romanesco broccoli (also known as broccolo romanesco, romanesque cauliflower, or romanesco) it is in fact a cultivar of the cauliflower. I love it for its fractal florets. It’s a magical plant with a wonderful taste, and like other brasicus, it can be planted in the early spring, handling some frost, late summer for a fall harvest or even late fall for a spring harvest… or with our warming climate, apparently a January harvest!What is the yellow one?
