There is an image of this cultivar on the Hosta Library. From the photo on the HL website, it appears to be an upright growing, medium size hosta with dark green leaves and creamy white marginal variegation.

The MyHostas database says that this is a misspelling of the cultivar, H. 'Iona'. Pictures of the two cultivars do look similar, however. We wonder if this has something to do with Jana Milbocker of Massachusetts who does educational presentations on hostas.
