Hosta 'Thunderbolt'
 

Originated by Allen Rick Crowder of Hawksridge Farms in North Carolina and registered by AHS/G. H. Alley in 2020, this upright cultivar is a sport of H. 'Elegans'. The foliage is dark bluish green (131A RHS Chart) with strong yellow green (144C RHS Chart) medial (center) variegation. Its broadly ovate to nearly round leaves are slightly wavy, moderately corrugated with prominent veins. The top and bottoms of the blades have a glaucous bloom.

The registration materials state: "...Bright yellow green centers are framed by extremely wide, blue green margins.  Nearly round leaves are corrugated, very thick and deeply furrowed.  Vigorous grower...Center color on older leaves tun almost white. Once the glaucous bloom fades the leaves are dull to very slightly shiny."

U.S. Plant Patent PP14,232 and PBR18193 QZ

This non-registered but patented () cultivar is a sport of H. ''. It was introduced by  in 2002. The mound reaches large size (27 inches high by 63 inches wide) with leaves that are heavily corrugated, wavy and somewhat unruly but with thick substance. Near white flowers bloom from mid-June into July.

According to The Hostapedia by Mark Zilis (2009), "Information published by the U.S. Plant and Trademark Office lists 'Thunderbolt' as differing from the similar 'Dream Weaver' by having a wider margin and more "deeply furrowed" leaves...Unfortunately, try as I might, I cannot see any difference between the two and do not agree that 'Thunderbolt' has a wider margin. I'll keep studying!"

 

An article by Warren I. Pollack in The Hosta Journal  (2020 Vol. 51 No. 1) titled Doppelgänger Hostas: Fancy Name for Look-alike Hostas, included a long list of hostas which various hostaphiles, published articles or other sources have indicated "look" the same. Some of these are, in fact, the same plant with two or more different names. Others are hostas that vary in some minor trait which is not immediately discernable to the casual observer such as seasonal color variations, bloom traits, ploidy, etc. So, as Warren mentions, hostaphiles may differ as to the plants listed but then, their opinions are based on visual observations and interpretations.
