We found this cultivar listed on the Hosta Lists website as a plant having "true" blue flowers.

Hosta Lists includes a quotation from an email from Jon Soucek of Ohio as follows: "I noticed your article on the flower color with the pics from Jerry Bryant - the hosta pictured was hybridized by my daughter and will be registered as 'St. Bernadette'. The color is true-blue as the sky and so is the scape. She is a graduate of Miami, Ohio in Botany and had the same professor as Kevin Vaughn. We are also patenting the plant as well as doing our own TC. The marketing of the plant is up in the air for now. It is fertile both ways."

However, an August, 2020 search of the Hosta Treasury which is the official hosta Registry website of The American Hosta Society, no information was found for this cultivar name or under the hybridizer name, Soucek.
