| Info | Mildred Seaver is one of the great characters of hostadom, and 'Sea Ebony' is one of her more interesting plants. It is a large plant with leaves of the darkest green that can reach twenty inches. It is one of the darkest green hostas outside of Mary Chastain's "black" ones, and is very hard to find. |
