Google it for more info. I have found the facebook page to be quite accurate. It is not a chat page...just plant id with botanical name from photo.
I'm thinking loosestrife as well, but that is only a guess. I looked it up and found that it grows throughout Europe and the Meditteranean region, so it probably grows in Italy. It's hard to tell if this is
Lysimachia vulgaris or the
Lysimachia vulgaris, var. davurica The petioles seem longer than in
Lysimachia vulgaris, but it is really hard to find the
davurica variety to compare. Also, the buds seem rounder and more fruit-like in your photo but maybe yours have already bloomed and those are the seed capsules? Anyway ... here are some shots of
Lysimachia vulgaris .
