Chou-fleur

Le chou-fleur est l'un des nombreux légumes de l'espèce Brassica oleracea du genre Brassica, de la famille des brassicacées.

It is an annual plant that reproduces by seed. Typically, only the head is eaten – the edible white flesh sometimes called "curd" (similar appearance to cheese curd). The cauliflower head is composed of a white inflorescence meristem. Cauliflower heads resemble those in broccoli, which differs in having flower buds as the edible portion. Brassica oleracea also includes broccoli, brussels sprouts, cabbage, collard greens, and kale, collectively called "cole" crops, though they are of different cultivar groups.
