Brassica oleracea

Pliny included what he called cyma among his descriptions of cultivated plants in Natural History: “Ex omnibus brassicae generibus suavissima est cyma,”[1] (“Of all the varieties of cabbage the most pleasant-tasted is cyma”).[2] Pliny’s descriptions likely refer to the flowering heads of an earlier cultivated variety of Brassica oleracea, but comes close to describing modern cauliflower.
