Might be a 'Krossa Regal'. A little off the typical shade/color, but in The Hosta Library, the second-to-last pic of 'Krossa Regal' has color a lot like your plant. Those super-long scapes are another reason I'm thinking 'KR'.

Don't ask me why, but I immediately thought of Rascal! The colour I guess, which I love. That's my uneducated guess....can't wait to see what is!

Krossa Regal is large, vase-shaped...and blue... that sometimes takes on some green as summer wears on (at least it does for me)...you mentioned low-mounding...this one is too light....very lovely nonetheless.

Look at those long scapes, very similar to undulata's flowers. Could it be an undulata seedling? Very nice looking hosta.
