By Olga Petryszyn. Leaves are upright, long, gracefully bowing, having a deep throat and unique dark color. It starts out a dark bluish-green coating with a very powder blue back. Mid season it turns blackish blue, making the leaves appear as if coated with coal dust. Grows quickly to 3 foot tall. Outstanding dark hosta that makes gold hostas look even brighter. Zones 3-9.
