Cabbage romanesco

The cabbage romanesco ( Brassica oleracea VAr. botrytis ) is a variety of Chou-fleur originating in Italy and more precisely in Rome. It is also called “broccoli with apple”.

Although it is about an old variety, its introduction in France is relatively recent, he is cultivated there into large since the Années 1990, especially in Brittany (areas of Saint-Pol.-of-Leon and Paimpol). Its marketing was spread starting from 1993 on the market of the expenses, then via deep freezing. Its economic importance remains however limited.

The cabbage romanesco resembles the Brocoli by its color green apple and the Chou-fleur by its compact form, but consists of a pyramidal whole of “florettes” laid out in spiral crowns. Its geometrical form is very particular and decorative.

The provision of the floral buds in regular spirals illustrates the laws of the Phyllotaxie.

An attentive examination shows that the number of spirals directed in the direction of the needles of a watch and the number of spirals directed in opposite direction are two numbers of the Suite of Fibonacci, the report/ratio of these numbers is an approximate value of the Golden section. Moreover its geometry Autosimilaire makes that it is often quoted like an example of Fractale natural.
