Chelone glabra /Snapdragon Family
These odd-looking flowers like to live near water, especially near streambanks. They are in the Snapdragon Family. There is a dark pink-flowered Red Turtlehead too. I got a laugh when I noticed the lower flower lip moving as if it were "talking," a bee was deep inside the flower! Note the bumblebee's head peeking out from the opening of the flower.
