A cross of H. 'Elatior' × H. 'High Noon' was registered by Olga Petryszyn of Indiana in 1999. It forms a giant size plant rising to 37 inches high and 88 inches wide. The leaves are broadly ovate and have slight corrugation. Its near white flowers bloom from late June into July.

According to The Hostapedia by Mark Zilis (2009), "Shortly before I viewed the magnificent specimen of 'Key West' in Olga Petryszyn's collection, she revealed that only one out of every six hundred of her seedlings made it to the registration stage."

From the Field Guide to Hostas by Mark Zilis (2014), "...makes a statement in any garden in which it is grown. Its rich coloration and massive size compels observers to stop and admire its magnificence."
