This sport of H. 'Blue Mouse Ears' was introduced by
Fransen of the
Netherlands. It has
thick leaves and grows into a miniature size hosta about 6 inches in height. The flowers
are lavender in color.
The Book of Little Hostas by Kathy and Michael Shadrack
(2010) says: "Will take some sun and is ideal for a ceramic
container. A good gravel mulch will prevent splashback and better show off this

Fransen reports that 'Snow Mouse' is the same as 'Mouse Trap'. The bright-white
center emerges in the spring and stays all season. There often is some green
speckling or flecks in the white center, either on newer leaves or later in the
season. Don't be surprised if you find plain blue-green leaves on both
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.
'Pure Heart' 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? Also, all the hostas on both lists are medially
(center) variegated except for H. 'Mighty Mouse' which has
List #1 -
H. 'Holy Mouse Ears',
H. 'Mighty Mouse',
H. 'Mouse Trap', H.
'Pure Heart' and
List #2 - H.
Mouse', H. 'Mighty
Moe', H. 'Minerva
Mouse Ears' and
H. 'Pure Heart'
