The nursery that grows U. Prosciutto also grows U. Naples Yellow and U. Naples Dark. Of the 3 the owner prefers U. Prosciutto. Don't go by my opinion I think most figs taste good. It is quite unusual. The fig itself has a very smooth, dark green skin with a pink interior.
All 3 have trunks as big as my leg. They have been growing in NJ zone 6 for over 30 years. Pruned and covered every year. U. Prosciutto ripens a little later than I would like, but if you are looking for a season extender it will do just fine.
