Hosta 'Blue Angel' 
Its almost impossible to adequately describe this magnificent Paul Aden creation. ‘Blue Angel’ is, in a word, breathtaking. It is a big, bold, blue, highly prized hosta that commands attention in any garden. Some have proclaimed it the largest of the blue hostas, reaching up to 3 feet tall and 6 feet wide in very rich soil, and whether or not that is true, it undeniably has a big presence.
