Romanesco broccoli (also known as broccolo romanesco, romanesque cauliflower, or simply romanesco) is in fact a cultivar of the cauliflower (Brassica oleracea var. botrytis), not broccoli (Brassica oleracea var. italica).[1] It is an edible flower bud of the species Brassica oleracea, which also includes regular broccoli and cauliflower. It is chartreuse in color and has a striking form that naturally approximates a fractal.[2] Romanesco has a nutty flavor and a firmer texture than white cauliflower or broccoli when cooked.[3][4]
