Jim Schwarz of
Jim's Hostas of Iowa (now owned by
Hostas of Wisconsin) registered this sport
of H. 'Treasure' in 1997. The
large size mound grows to about 24 inches in
height with a spread of 60 inches. Its leaves are broadly ovate,
heavily corrugated and have thick substance. Very pale lavender
flowers borne in dense clusters bloom starting in late June.

H. 'Sieboldiana'-type that does
not develop spring desiccation burn? Try 'Garden Treasure'."
