hybrid of H. 'Blue Moon' was registered in 1994 by
Charles Seaver of Delaware. It forms a large size hosta about 21 inches tall and 60

Hosta Journal (2010 Vol. 41 No. 1) makes comments about
H. 'Deep Blue Sea', "Charles Seaver registered this 'Blue Moon' seedling in

the time it blooms later in the season, the wax has washed off and the leaves
are dark green and very shiny."
