Originated by Roger and Ann Bowden from Devon, England and registered on their behalf by the Registrar, Gayle Hatley Alley for The American Hosta Society in 2019. This cultivar has H. 'Sieboldiana' in its background but the exact parentage is unknown. It is an upright growing, large size hosta about 24 inches high by 62 inches wide with moderate yellowish-green (138A) foliage.

The leaves are broadly ovate, slightly convex cupping, moderate corrugation and have a satin sheen on top. Near white flowers bloom from late June into July on scapes about 34 inches tall followed by viable seeds. This cultivar is part of the "Devon Series" of hostas.

The registration materials state: "...Very tightly packed clump of numerous flowers top the tall scapes. Very fertile.."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Origin: H. 'Hadspen Blue' hybrid.. .Slow to establish but eventually will become one of the largest hostas...A superb background specimen or for a woodland garden."
