caption: The image shows a common polypody fern growing out of a rock in the woods, surrounded by other rocks and grass. The fern is a vibrant green color, with its long, thin fronds cascading down from the top of the rock. Its leaves are a deep, lush green, and its veins are visible along the edges. The other rocks in the background are a mix of grey and brown, providing a stark contrast to the bright green of the fern.
