An Imposter?

In the corner of the car park at Woodside Walled Garden today I found a patch of weeds - the usual suspects, sorrel and sticky willies (goose grass, it you prefer), and this geranium. Good, thought I, that will do for WildWed.

Looking at it later,  I saw a strong resemblance to one I grow in the garden.  So I got out the Wild Flower Book, and it was in there. Then I read 'garden escape .. from South West France'.  Well, I don't think  it hadn't travelled any further than from the nursery garden next door. 

So it's suspect, but I will enter it anyway, hoping Cailleach will be kind and let it in.
