Weed

I don't have a big garden - it is mainly stones, being of the mediterranean style - but the weeds still manage to appear, pushing up through the membrane etc. So, today, a lovely warm day with not so much breeze saw me out there trying to get rid of some. Had loads of visitors to disturb me (thankfully) which was very pleasant.  
Done about half and now it is red wine and feet up time!
No idea what the pretty little purple weed is but thought I'd blip it for posterity before it went in the bin!
