Blue Hawaii Hosta – Like it’s tropical waters, ‘Blue Hawaii’ boasts a rich and powdery sky blue color. It’s leaves have thick substance and are intensely glaucous on top and bottom. This tall Hosta reaches up, bringing the sky to the earth. ‘Blue Hawaii’ is the result of one of Olga’s goals, to create a blue hosta that stays blue from early spring until mid August. Blooms heavily in July with mounds of white flowers. This is a very stately cultivar. Give her a special spot, away from overhead sun.
