This one is a total mystery to me. I have no idea what it is. I have not altered the photographs in any way. I know that the unusual colouring may be the effect of the low sun of the late afternoon passing through the leaves and other parts. It was growing on a piece of un-tended waste ground which may at one time have been a kitchen garden (an area close to a Victorian building). So it could be a cultivated plant or a wild one. It seemed to be growing in a creeping way along the ground – a bit like a pea without support. It was difficult to tell because I had to view it over a fence and couldn’t get up close. I used a zoom for the pictures. The blue-purple colouring gives it a kind of alien look. Perhaps you recognise it? I’d love to know what it is.
