Here is a motherwort (Leonurus cardiaca) leaf. This particular leaf is about 45 mm wide by 46 mm tall, but the leaves can get about 3 times larger than this. Native to Europe and Asia, this plant is now found throughout the world due to its medicinal uses. The Iroquois have used it to aid digestion and as a tonic for nerves.
