The word Costoluto in Italian means ribbed and the various ones are named for the region from which they came.
When Roberta in Italy offered to send me some traditional Italian varieties I told her to please not send any Costolutos.
Personally I've only grown the Genovese ( from Genoa) and Fiorentino( from Florence) and could seeno real difference between them.
If anyone should know about the Parma one it would be Roberta, since she lives in Parma.
She said she'd send me a special treat from Parma with the seeds, so am I wrong in thinking something to eat, or would it be Costoluto di Parma?
If something to eat what is Parma noted for?
Carolyn, who got the seeds from Turkey today but not yet the ones from Italy.
