This white edged sport of H. 'Northern Halo' was registered by Van Wade of Wade and Gatton Nursery (Closed 2019) of Ohio in 1999. It forms a large size (24 inches high by 70 inches wide) mound and has thick substance to its leaves. The near white flowers are borne from June into July. They have a pale lavender stripes on the petals and bear viable seeds.

According to The Hostapedia by Mark Zilis (2009), "...'American Halo' was selected as an improved form of H. 'Northern Halo', a much-maligned cultivar with several divergent clones."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Slow to establish but eventually becomes a huge mound...Winner of the 2002 Alex J. Summers Distinguished Merit Hosta Award...Larger than its parent with a wider leaf margin."

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.

H. 'American Halo', H. LEPRECHAUN'S LOOT, H. 'Northern Exposure' and H. 'Northern Halo'.
