"Romanesco broccoli resembles a cauliflower, but is of a light green color and the inflorescence (the bud) has an approximate self-similar character, with the branched meristems making a logarithmic spiral. In this sense the broccoli's shape approximates a natural fractal; each bud is composed of a series of smaller buds, all arranged in yet another logarithmic spiral. This self-similar pattern continues at several smaller levels.
The vegetable is rich in vitamin C, vitamin K, dietary fiber, and carotenoids." from en.wikipedia.org/wiki/Romanesco_broccoli
