The viewer is far down a well. Perhaps the well is full of clear water, but I imagine it could also be empty. The well is so old that the walls have softened and deteriorated, moss has turned to dirty and the dirty has provided a haven for the roots of these flowers. Hydrangeas line the well walls in this imaged and impossible scene. There’s a gentle current of water or wind within the tunnel and it’s a bright sunny day above the ground.
