OK. I admit I took this photo last year, but I still like it. It was taken inside The Royal Botanic Gardens (AKA Kew Gardens). The flower's common, but I dig the way you can see dew drops. We arrived there right when the gardens opened, which gave us a pristine view of pretty much everything (and lots of opps to shoot pics without strangers in the background - a real treat).
