There is an image of this cultivar on the Hosta Library. From the photo on the HL website, it appears to be a small size (12 inches high by 28 inches wide) hosta with frosty green leaves and yellow and white streaked variegation. This cultivar is a seedling of H. 'Fascination' × H. 'Elegans'. Very pale lavender flowers bloom from July into August. It is a non-registered hosta originated by Rick Goodenough of Massachusetts and is used in his breeding program. 

An article by Rick Goodenough in The Hosta Journal (2012 Vol. 43 No. 1) states that, “A relatively recent release, ‘Leaping Lipizzan’ is a strong breeder that turns out a high percentage of quality, streaked seedlings…Seven of those terrific seedlings include ‘Breeder’s Cup’, ‘Scalloped Potatoes’, ‘Dover Downs’, ‘Suffolk Downs’, ‘Gran Premio’, ‘The Stone Horse’ and ‘Belmont Stakes’.

...While ‘Leaping Lipizzan’ has some blue tones early in the season, ‘Dover Downs’, ‘Breeder’s Cup’ and ‘Suffolk Downs’ all have stronger early season blue. H. ‘Dover Downs’ features leaves with a more elongated form and a nice point on the tip, as well as wonderful wavy edges.

...At the time I planted my ‘Leaping Lipizzan’ test seeds in 2008. I shared the same seeds with numerous folks who wanted to try them…Trudy Van Wyke…has named one of these fine blue streakers ‘Hosana’. Jeff Moore has an interesting and fairly rare yellow streaker from this lot that he calls ‘Stewball’ from the Peter, Paul and Mary song about a racehorse.”
