Inc. of Michigan in 2000, this is a sport of H. 'Sum
and Substance'. This giant size (29 inches high) mound has shiny,
dark green foliage that curls and is somewhat unruly. Pale
lavender flowers bloom on 48 inch tall scapes from late July into August.
The Hostapedia by Mark Zilis (2009), "I'm sure that a properly fertilized, well-watered
specimen of 'Vim and Vigor' will become much larger than what
I've seen so far. In fact, it should exceed the dimensions of
Van Wade's famous specimen of 'Sum and Substance'."
An article by
Warren I. Pollack in
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.
