A new one that Ran tells us is a much bluer version of the original, which was a medium green!
Hostas are mysterious things, and Ran Lydell's big-growing favorite 'Arch Duke' seems to have mutated to a form with extra wax on the leaves, and is now done up in a nice blue paint job. It is a big one, with leaves over a foot in length when mature. 'Blue Arch Duke' should be a great plant for hybridizing too, as it has some nice traits to pass along.
