Mark Zilis of Illinois registered this sport of H. 'Blue Mouse Ears' in 2011.
The miniature size plant grows to around 6 inches in height with
a spread of around 14 inches. The leaves are medium blue-green
and are heavily rippled, slightly cupped, moderately wavy and
nearly round with a cordate base. Medium lavender, tubular
flowers bloom in July. The plant turns dark green by late July.
Warren I. Pollock
wrote comments about the many sports of H. 'Blue Mouse Ears' (which he termed
Hosta Journal (2012 Vol. 43 No. 2). He stated,
Fransen introduced 'Dancing Mouse'.
Its blue-green leaves have a wavy yellowish-green border that
darkens to pale green as the season progresses. He states
that the ruffled margins and unusual color combination make it different from
others in the series...(Is 'Dancing Mouse' a variegated 'Ruffled Mouse Ears'?)"
Mark Zilis registered 'Ruffled Mouse Ears', which has wavy blue-green leaves.
Possibly it's 'Dancing Mouse' without variegation."
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.
