Gretchen Harshbarger of Iowa registered this open-pollinated seedling of H. 'Tokudama Aureonebulosa' in 1981. It forms a large size (19 inches high) plant with thick substanced leaves and near white flowers borne from late June into July followed by viable seeds.

According to The Hostapedia by Mark Zilis (2009), "The thick substance, attractive corrugation, and bright gold foliage color make 'King Tut' one of the best non-burning gold-leaved cultivars...sibling to 'Blondie' and 'Treasure'..."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Slow to establish...among the best of the golden yellow-leaved Tokudama Group as it forms a shapely mound. Also notable for throwing good offspring...The flower scapes are tall for a hosta of this ancestry."

A Photo Essay article by Steve Chamberlain in The Hostta Journal (2010 Vol. 41 No. 1) makes comments about H. 'King Tut', "Gretchen Harshbarger registered this hybrid of 'Tokudama Aureonebulosa' in 1981. It is a reliable yellow hosta with good substance and a hint of green that gives the leaves an unusual appearance. It also has proven to be a useful pod parent in my hybridizing program."
