This cultivar from Steve Schulte of Wisconsin is a non-registered sport of H. 'Undulata Univittata'. The mound grows into a medium size hosta about 16 inches in height with a spread of 36 inches. Its medial (center) white variegation is much narrower than that of its mother plant. The leaves are wavy, curled at the tip and have smooth texture. Pale lavender flowers bloom in July.
