The nomenclature surrounding Hosta longipes is as confusing as the number of forms. Mark Zilis in his book, "The Hosta Handbook" lists the features as: small to medium-sized mound of green foliage; a highly variable, common Japanese species. Mound size: 10" high by 20" wide (16" by 40" for large form). Leaves 8" long by 5" wide, shiny, medium to dark green; very shiny underneath; slightly wavy; ovate blade with a slightly lobed base.
