Originated by LeRoy Davidson of Washington, this non-registered cultivar is of unidentified parentage but has H. longipes in its background. It is a small size hosta with green foliage that has purple flower scapes and petioles.

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term iwa as rock, Iwa Gibōshi or H. longipes.
