Hello everybody, I only just subscribed!
I work at the agriculture university in turin, and I'm doing researches about historical gardens...
Right now a colleague asked me to help him identify this plant that he says it's a lithodora but i'ìm not so sure about that... and i'm having quite a hard time to be honest....
Could someone please give me a hint??
thank you ever so much and greetings from Italy!
