I saw these lying on our patio. This was a bit of a surprise. I believe they are Maple leaves and if I’m correct I don’t really know where they came from as I don’t think we have any Maples on our property. Maybe they were blown over from a neighboring property? Still they were very colorful and I couldn’t resist putting a few of them together on top of one of the stones, which make up our patio. I think the colors are offset by the greys of the stone.
