The most interesting characteristic of this wetland plant is the leaf variation, which makes it appear as if two plants were combined to make one.

At the base, are rounded compound leaves of different sizes on long petioles, and hugging the main stem are three lobed leaves, which are deeply serrated.

The yellow 5 petaled flowers are born at the end of the stems in May.

Native Americans found that chewing the leaves of Large Leaf Avens was useful during childbirth and that the roots were good for producing a tea to cure stomachaches.

This plant can be found from Alaska to California and east to Idaho and Montana; it is especially concentrated in USDA zones 1-9.
