Just to make worse it all...Cannizzaro is the usual spelling of this italian surname
hahahaha!! Nice one alevan!
Indeed there are websites that has variations of the spelling ..... some people seriously did write names in whichever way they wanted ------ which is ridiculous haha.
It was listed as Ctt (C.) Porcia 'Cannizaro' when it was awarded (that's the only time there is an actual record of a cultivar name) so it may be bad Italian, but that's the version in the record books. It isn't the first (or last) time that a misspelled name gets cast in concrete.
