The Moon of Blue and Yellow Flowers

Is September I think, as I dredge my memory for youthful and possibly non-pc reading. Asters and goldenrod rather than salvia(?) and marigolds but the flowerbeds brought the thought to mind.
It was dull, cold and rainy today and although I didn't notice at the time this photo seems to show that the lights were on in the park at 10 am. Sigh. Maybe it's an illusion.
