As the name might imply, this is a giant size (28 inches high by 76 inches wide) hybrid of H. 'Empress Wu' × an unidentified hosta that was registered by Linda Port of Illinois in 2013. It has flat, slightly blue-green leaves and bears pale lavender flowers from June into July. This cultivar sets viable seeds. In the spring, it emerges greenish yellow in color but changes to blue gray as the season progresses.
