Romanesco Broccoli

Browsing in the produce section of Berkeley Bowl I was transfixed by spiral nature of Romanesco Broccoli, an edible flower in the broccoli family.  The flower’s form approximates a natural fractal because each flower is composed of a series of smaller flowers, each arranged in a logarithmic spiral. This pattern is replicated in smaller sizes at different levels on the flower. The pattern is only an approximate fractal since the pattern eventually ends when the flower size becomes really small. The number of spirals found on the head of Romanesco broccoli is always a Fibonacci number.

I brought a nice head of Romanesco Broccoli home, and photographed it on white seamless using a macro lens with an extension tube to get close enough to show the spirals. The version above is in black and white, with the color version below.

By the way, I recently saw Star Wars: The Force Awakens. Some Romanesco Broccoli is featured in The Force Awakens. No, it is not the mystical, Fibonacci-driven world that Luke retires to (in case you wondered). The Romanesco Broccoli is a mere extraterrestrial garnish in the exotic drink Rey is handed in the scene in Maz Kanata’s Castle (along with a weird-looking fruit, a Citron, which coincidentally I also photographed recently). I guess the Disney stylists for The Force Awakens also wandered in the produce aisles at Berkeley Bowl!
