United States Patent: PP24009  (2013)

Abstract: A new and distinct Hosta cultivar named ‘Ben Vernooij’ is disclosed, characterized by distinctive round foliage on thick petioles, vigorous plant habit and strong foliage, with good resistance to environmental stressors and large flowers. The new variety is a Hosta, typically used for outdoor ornamental purposes.

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. 'Autumn Frost', H. 'Ben Vernooij' and H. 'Permafrost'.
