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. 'Morning Light' is included on two look-alike lists in this article. Following an algebra rule I learned in the last century, if A=B and B=C, then A=C so all the hostas on both lists should be look-alikes...right?

List #1 - H. 'Lady Isobel Barnett', H. 'Sum It Up' and H. 'Sum Total'

List #2 - H. 'Sum It Up', H. 'Sum Total' and H. 'Tiffney's Godzilla'
