'Ocean's Fury' is a very blue, intensely corrugated and deeply cupped hybrid of 'Tokudama' X OP. The leaves are broadly ovate and have good substance. It is the result of Don Rawson's breeding program with the goal of producing hybrids which remain blue all summer, even in full sun. Somewhat slow growing, but unmatched for blue color late in the season.

There is an image of this cultivar on the Hosta Library. From the photo on the HL website, it appears to be a large size hosta with intensive blue-green leaves with a glaucous bloom on the bottom. This non-registered cultivar was originated by  of Michigan.
