Mystery tomato variety

[Mitzi]

Wonder if anyone can help? I have been given some tomato seeds. The person who gave them to me said it's an Italian variety, the first name begins with C and the second is something like Formentera. He also said they grow OK outdoors and are expensive.

My Google-Fu is not up to the challenge. Anyone got any suggestions?

(N.B. I wouldn't be surprised if what he told me is unreliable.)

Costoluto Fiorentino ? Maybe?

Costoluto Fiorentino ? Maybe?

Excellent suggestion; thank you. I'll ask him if that rings a bell.

I just wondered if the 'they were expensive' was a twist on they 'cost-a-lot' - like a cryptic crossword clue LOL

You were spot on; that's exactly what it is.

I don't know why he said they are expensive; perhaps he got ripped off!
