Hello, Hello, What's this then?

The day before yesterday we passed a tree stump or log of that ilk on which was growing a most luxurious plant with light green colour that was very distinctive and shone in the sunlight. It had long serrated leaves and was a fairly bushy plant. We were amazed at its capacity to grow in such an unusual place.

Today I saw a similar looking plant growing in the cratch of a moored boat.


The boat had no license, no visible name but was identifiable by number. The amount of vegetation growing on it was amazing. I suppose it was what Grannny Buttons would call a hippy hutch.



Can anyone identify these lovely pretty plants to confirm my suspicions? [Now authoritatively identified as cannabis among the tomatoes, ED]
