Everyone saying it’s photoshopped and some saying that it’s not growing anywhere else, zoom in on the photo and you’ll see the flowers growing in the background still on the foot path and large bundles of weeds have also sprouted on the other side. If it was a photoshop it’s done very well. Each flower, stalk and blade of grass casts a shadow on the footpath. I can’t tell where this is at the moment but it looks like Southern Europe, Italy or Greece, my guess. The sun high and it’s a clear day, the white from the wall is causing a distortion effect on the lens, causing other colours to appear brighter - the flower petals themselves mostly. But I don’t think this is photoshopped, you’d be surprised how quickly nature can take over when there are no humans around.

Here is a photo, tell me if you think it’s photoshopped or not.
