bigger as it matures."
The New Encyclopedia of Hostas by
Grenfell (2009) states in its Miniature Hostas chapter: "The leaves
retain the attractive variegation into early autumn. Slow to
moderate growth rate...This delightful recent introduction is
already captivating the collectors of mini hostas."

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, "Shady Characters Nursery describes 'Cat and Mouse' leaves as 'chartreuse interior circled
by an uneven blue-green margin. Lighter shades of green appear where the two
colors overlap'. The center becomes much brighter and distinct later in the
growing season. Also, the margin turns green later in the season. Furthermore,
don't be surprised if your 'Cat and Mouse' is not stable, reverting to
plain-leaved BME ."
