The way I read it, there could be in fact two bouquets: one of red roses and 'oeillets' (don't know the English for that one) coming from the florist or a garden; and the yellow dandelions look like they could have been gathered by a kid.
Looks very sad to me: some sort of memorial, commemoration of an accident? A lady and her child could have lost their husband and father here? Or someone's ashes could have been spread here? I can definitely see people crying at this spot.
As for the photo, well, it's correctly exposed and framed; certainly unconventional but it suggests a story (or stories), you see, it made me stop here for a while. So, it must be good
