This distinctive medium hosta showcases very dark green leaves that are thick, shiny, corrugated and folded. The lustrous foliage stands upright in an elegant vase-shaped silhouette, with the textured leaves catching light beautifully to create striking visual interest in shade gardens. Pale purple striped flowers emerge in July, adding a soft contrast to the rich, dark foliage. With its exceptional leaf texture, unique corrugated surface, and graceful upright form, Midnight Oil stands out as an extraordinary specimen that brings sophisticated beauty to any garden setting.
