This plant which is probably a form of H. longipes 'Urajiro Iwa' was purchased from Japan and registered by Mark Zilis of Illinois in 2009 and re-registered with new data in 2018. It grows into a small size hosta about 8 inches tall by 17 inches wide with leaves that are slightly wavy, lanceolate and dull on top. The lavender flowers are borne from September into October.

The registration materials state: "...wild collected form of H. longipes; low, dense mound of foliage is attractive all season long, but its flowers in September and October make it one of the best miniature hostas for fall effect...."

From the Field Guide to Hostas by Mark Zilis (2014), "...notable for its very late flowering time, one of the latest of all hostas,...typifies the diversity found in H. longipes..."

\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 and the term urajiro as white-backed or white underside.
