Mighty little hosta with round, blue-green leaves surrounded by a wide yellow border that ages to creamy white. In late spring, the clumps are topped with short spikes holding a paucity of dark lavender flowers. H. ‘Mighty Mouse’ is very similar to H. ‘Frosted Mouse Ears’, another member of the Mouse family.
Small: Differs from its mother plant by its white-margin (yellow early), bluish green-centered leaf color; should become a small, dense mound of foliage.
