Costoluto Fiorentino is a nice tomato. Costoluto means "ribbed" in Italian, Fiorentino basically means "Florentine", or of Florence. Red, medium-sized, slightly flattened beefsteak. Heavily ribbed fruit. It's superior to another "Costoluto", "Genovese".
CF is a famous old Italian variety but I suspect it has been hybridised over the years, unfortunately. It's not as full of flavour as it used to be.
