Described as having a 'Fortunei' background, this cultivar was registered by The American Hosta Society in 1986 on behalf of the originators, Gus Krossa of Michigan and Alex Summers of Delaware .

This medium size (17 inches high by 45 inches wide) mound has dark green foliage with white marginal variegation. The leaves that are moderately corrugated and slightly wavy. Pale lavender flowers which are bunched near the top of the scape bloom from late July into August but it does not set seeds.

According to The Hostapedia by Mark Zilis (2009), this cultivar "...maintains its distinction among hostas due to its upturned, white margins...For a number of years, specimens of 'Gloriosa' in some gardens incorrectly bore the name H. rhodeifolia albo-marginata."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Although the variegation is usually uniform, it occasionally throws white streaks toward the midrib. Vigorous, easy to grow...Leaves have a distinctly upturned stance when mature. The raceme is bunched toward the top of the scape."

"Plant's margin is uniform and very narrow. Smaller than most other white-margined forms of H. 'Fortunei', but some authors do not believe it is related to the latter."
