Seems to me this species listing should properly reflect all forms of it:
clausa var. clausa
clausa var. normalis
clausa var. stolonifera
All three are in cultivation with the most common one being var. clausa.

This unique hosta has narrow blue leaves with intensely wavy margins. The leaves are the most blue in spring; as the season progresses the leaves become more blue-green. It's a seedling from 'Curly Fries' and is patented.

I believe "Shadowland" should not be shown as part of the plant name. It is a trademark, but the plant name is simply 'Hope Springs Eternal'.
