Hosta Royalty will form a small to medium mound, reaching 25cm to 40cm in height with a spread of up to 60cm at maturity. It features yellow leaves that form a distinctive crown of greenish-yellow, narrow, wavy-edged foliage. Exhibiting a fairly upright growth pattern, it produces lavender flowers elevated well above the foliage on green scapes, doubling the height of the crown to approximately 80cm late in the summer season.
