Hosta Sun Mouse forms a small mound, reaching a height of 15cm-20cm and spreading up to 30cm at maturity. It is similar to Blue Mouse Ears but features brilliant yellow leaves and is slightly shorter and wider. The bright yellow foliage gives the plant an appearance of glowing with inner happiness. This petite plant is ideal for dark, bare corners, as its colour remains vibrant even during the hottest days of summer. In mid-summer, purple flowers emerge on scapes that extend up to 45cm above the distinctive golden foliage.
