An acorn cup is the cap-like structure that holds the acorn on the oak tree. It's a small, bowl-shaped structure, often textured with scales or bumps. Unlike the acorn itself, the cup is not edible and is left behind after the acorn falls. Think of it as the tiny hat of the acorn, providing protection and support. It varies in shape and size depending on the species of oak tree. These cups can be used in crafts and decorations, adding a natural, rustic touch.
