Need measurements on leaf width and height, overall plant dimensions, any detail you can provide about the flowers - color, pattern, height, and age of plant if you know.

Actually, I was going to say it looks like Hyacinthina... before I saw your question :) That was easy! Check the backs, they should be white-ish. This pic is from 6/20, so that's why no blooms showing.

Just a compliment for Eleven - beautiful picture of beautiful, picture-perfect hostas. Love it. :D

is pearl lake an option?

Ken has a good eye. The leaves of your plant do appear to be more heart-shaped than Hyacinthina. Leaf color and texture are very similar for both right now, so you'll need to check the backs of the leaves. But if you saw it earlier in spring, Pearl Lake begins as a bluer hosta. Here are pics of Pearl Lake for comparison, first from 6/11 then from 6/26.
