As already stated, when the cauliflower was first cultivated in France the island of Cyprus was the only place where it was known to seed, and for a time the plant was known in England under the name of Cyprus colewort.

A full account of these crosses may be found in the Revue Horticole for 1880. The following remarks, by Mr. A. Dean, of England, on a case of apparent crossing in the cabbage tribe will be read with interest: "A very pretty conical-headed plant of a colewort was allowed to run to seed, but nothing else of the same family was known to be in flower for a distance of at least several hundred yards.

It is probable that bees, which travel long distances, had somewhere found some sprouting in Broccoli flower and had brought pollen from those to the colewort plant in question."
