When is a weed not a weed ? Dumb question to ask a gardener - "it's always a weed!". But, when you ask a photographer, well, you might get a different answer. With the right lighting and aperture, and when the bokeh works out, that weed might just be considered art, or at least a photo worth posting. As they say - "beauty is in the eye of the beholder".
