Dyschoriste oblongifolia, Oblongleaf Snakeherb or Pineland Twinflower
Several Native nurseries carry this flower. It was noted in two sources as being a host plant for the Buckeye Butterfly, who has more hosts than any other butterfly I know.
I am content to leave it to its own devices in the wild gardens.
Note the spotted nectar guides, the feature that enabled identification.
Tomorrow I was going back to the meadow and smell and taste it to see if I could find any other traits. It's easier to rule out what a plant Is Not on the way to find the true name.
Thanks to Stone who Gardens-in-the-Sand for inspiring me to keep looking.
