A seedling selection by
Shuichi Hirao of
Japan, this cultivar was registered by
Peter Ruh of Ohio in
1997. It forms a large size (25 inches high) mound of floppy foliage.
The leaves are slightly shiny on top and very shiny on the
bottom with slight corrugation.
This cultivar is part of the "Hirao
Series" of hostas.
The Hostapedia by Mark Zilis (2009), "I often state that 'Hirao Supreme' is slightly less
spectacular as a specimen plant than 'Hirao
Majesty', but still worth growing. Also, it has been a
better breeding plant."
