Hosta Marshmallow Sky forms a medium-sized mound reaching 38cm-50cm in height, with a spread of up to 75cm at maturity. This variety features striking white leaves with a dark green margin. The leaves are relatively upright on an open clump, characterized by very wavy edges. Lavender flowers bloom from July into August and are held well above the foliage on scapes that can reach up to 90cm. This is a stunning Hosta that would make a valuable addition to any collection.
