Little White Flowers

A beautiful morning again, crisp but sunny and clear blue sky...........this little plant has appeared in my garden and I have no recollection of planting it, looks like a chrysanthemum, but very small and low growing, about 2 feet high........I am assuming it is a wild flower??  Anybody know??

Thanks for all the interest in yesterday's mystery macro... it was in fact a pinky purple spare pair of reading glasses, looking at them from the hinged arm, you can just make out the lenses to the right....a couple of people commented on the hinge but no-one guessed it...all good fun :))
