Near white flowers on 24in scapes. Leaves are thick, rich dark blue, deeply cupped and heavily corrugated. In fact, no other hosta boasts such deeply cupped leaves. Depth of the leaf cupping can be up to 4in and the powdery gray underside of the leaves is often visible because of the cupping. Named so, because a dog was seen drinking water from one of the leaves. Light to full shade. Slug resistant.
