I live in a victorian house and all of the houses have back alley ways with back entrances to the gardens.
Once upon a time the dustmen used to come all around the back alleys and take the metal dustbin empty it and return it to your garden.
Now we have nasty plastic bins littered all over the pavements but that's so called progress.
Anyway, I'm not posting about the bins, I'm posting about this plant that has decided it is a good place to grow at the bottom of the wall in the alley.
Last year it was just leaves but this year it has produced a sort of flower.
Any ideas what it is?
