Your plant is still alive?
This is an urban myth.
If you go to the high rhine area, you will find Puntarelle, carciofi, pesce (they are a bit more hairy), pepperone, fave, albicocce, melanzane ... and all that other stuff that rises under the italian sun. Also peperoncini.
Pesce noce are quite rare, but there are also some. I also saw a khaki tree a few days ago!
The only really difficult thing is il fico. The tree grows, but the fruit takes too much time to mature. When autumn comes, most of the ficos are still not mature.
