Hosta Sun Mouse will form a very small mound of 6"-8" in height, with a spread of up to 12", at maturity. Hosta Sun Mouse similar to Blue Mouse Ears, but with brilliant yellow leaves and a little bit shorter and wider. It seems to glow with an inner happiness through its bright yellow leaves. This diminutive plant is perfect for dark, bare corners. The colour will not fade, even during the dog days of summer. Purple flowers appear in mid-summer held on scapes of up to 18" above that wonderful golden foliage. Not slug resistant nor sun tolerant.
