The background of this cultivar
is uncertain but it appears to be either H. longipes or Hosta rupifraga. 'Late Jewel' was
Dr. Ralph (Herb) Benedict of Michigan but registered in 2010 by Rod Kuenster of Iowa. This medium size mound is about
tall and 21 inches in diameter with smooth textured leaves. The
foliage is broadly ovate, heavily rippled, deeply wavy and very shiny on top
with twisted tips which point downward. Its
medium purple flowers bloom from mid-August into September.
The Hostapedia by Mark Zilis (2009), "...is listed as a "giant"...but
it is not. At maturity it becomes a medium-size mound..."
