This classic cultivar consists of
a large mound of green foliage and fragrant flowers later in the
season. It was originated by John Grullemns at Wayside Garden in Ohio as a hybrid of
Hosta plantaginea and
Hosta sieboldiana
in the early 1960s. At that time it was also granted a

wavy, shiny foliage of a medium green color. The leaves are
slightly corrugated and are very shiny on the bottom. True to

numbers in mid August into September.
