Hosta Metallic Sheen will form a large mound of 28"-32" in height & up to 60" in width at maturity. It has very thick metallic grey-blue leaves, that age to dark green. The thick metallic blue leaves make a showstopping clump in the garden. In July to August, the clump is topped with light lavender flowers on 36" scapes. Thick, ridged leaves allows this one to be slug resistant. Only partially sun tolerant. Keep out of midday sun.
