Back in the days when fractals where the most fashionable thing, I had heard of fractal cabbages, and seen pictures of them. However, they are typically not available in French or American stores, so I didn’t see a real one until noticing that they are very common in Swiss supermarkets. Here’s a picture of one, but I should say that pictures do not quite convey the actual feel of seeing and handling this vegetable (not to mention eating it — and it is indeed quite tasty). The diameter (of horizontal cross-sections) of the specimen displayed here is between 10 and 15 centimeters, and the height is slightly larger.
