Hosta Marshmallow Sky will form a stunning, medium-sized mound reaching 38cm-50cm in height, with a spread of up to 75cm at maturity. Originated by Marco and Joyce Fransen of Fransen Hostas in the Netherlands, it is a sport of Hosta Orange Marmalade. This variety features striking white leaves with a dark green margin. The leaves are relatively upright on an open clump, characterised 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.
