No idea, I don't recognise those leaves at all.

I've just had aquick Google (as you do ) and some images for black nightshade show some similar looking leaves - most are like potato leaves but one in particular looks very like yours.

See what you think.

I agree, black nightshade Solanum nigrum not to be confused with deadly nightshade, Atropa belladonna. Black nightshade was used as a medicinal herb being sudorific, analgesic and a powerful narcotic, but dangerous as some strains can be fataly toxic, particulary to children and animals.

Thanks. Guess I won't be making wine out of them, then!

Hi Pach

I had the same plant growing this summer, two of them and like the previous thread at first i thought they were some kind of potato but then the black berries appeared and someone informed me that they are some kind of nightshade - dug them up rather quickly!!! Never had them before - just appeared this summer......

You're on the right lines as both plants are related: Potates are Solanum tuberosum After potato plants flower, some varieties produce poisonous small green fruits that look like green cherry tomatoes and which contain a large amount of the toxic alkaloid solanine. Tomatoes are Solanum lycopersicum. If you rub a tomato leaf between your fingers, the bitter odour is the poisonous alkaloids it produces. Needless to say tomato fruits are fine to eat!
