 I went for a walk in our plant several days ago.Suddenly I saw something that never seen before it looks like lemon. But this is not it.I asked ... I was explained that is not for eating.They say it is monkey apple. It was very interesting for me.Because I dint hear that any monkey lives in Caucasus.Why is it named monkey apple..?
