Hosta Xanadu will form a compact mound, reaching a height of 20cm-25cm and spreading up to 50cm at maturity. The leaves emerge as creamy yellow in spring with broad green margins. By mid-summer, the leaves transition to creamy white with green margins, featuring lighter green streaks where the leaf centre and margin overlap. The flowers are pale purple, borne on distinctive purplish-red scapes that reach 45cm in height and bloom throughout July.
