    Native in the Pacific Northwest from the Aleutian Islands south to Chihuaha; and in the northeast from Newfoundland south to Maryland. Was previously classified as A. pedatum until 1991. A. pedatum does not grow well in the Pacific NW, loses vigor, and dies easily.

    It is said that if a girl can hold a maidenhair stem without causing the leaves to tremble, she is chaste.
