Hosta Smimmy Shake forms a medium-sized mound ranging from 36cm to 40cm in height, with a spread of up to 80cm at full maturity. It features a flat-top mound consisting of rippled and twisted light green foliage. The leaves exhibit a chartreuse to yellow hue when cultivated in bright locations. They are elliptical to oblong in shape, slightly cupped, and positioned horizontally on reddish petioles. The ripples and twists of the leaves accentuate their white undersides, creating a dynamic visual effect. This distinctive leaf movement makes Hosta Smimmy Shake an excellent choice for container specimens. During the summer, lavender flowers emerge on scapes that reach 60cm in height.
