If you look closely it is really fairly difficult to confuse Crocus sativus with any other crocus species. The flowers are THAT distinct. Although other crocus and even other genera are given the common name of “Saffron”, the true saffron comes ONLY from C. sativus. Well, the style branches are longer, so you get more saffron per flower, which is probably why it wound up as a cultivated plant. Any of these will do for risotto alla milanese. http://s1265.photobucket.com/user/paridevita/… http://s1265.photobucket.com/user/paridevita/… http://s1265.photobucket.com/user/paridevita/… Bob Nold Denver, Colorado
