I know what you're saying. Roma- what? Romanesco. Also known as Roman cauliflower. The name may not be familiar, but it's flavor profile will be. It tastes like a cross between broccoli and cauliflower, but a bit more delicate than either. It is the edible flower of the species Brassica oleracea. It is available only for a brief time of the year, between September and December. It is easily the most stunning vegetable I have ever seen. A whole head of romanesco looks like something out of an art museum.
