Hosta 'School Mouse' is the latest introduction in the 'Mouse Ears' series of sports. The edge of Hosta 'School Mouse' is bright yellow and features a nice edge ruffling. It features thick leaves that make it slug resistant. Grow it in a container, fairy garden or outside in either a woodland garden or shady rock garden. Hosta 'School Mouse' is smaller than Hosta 'Mini Skirt', and the edge remains yellow instead of aging to creamy white. Colors will stay fairly consistent and bright throughout the season. In early summer, you will see proportionate scapes with lavender flowers.
