Forget-me-not

My great-grandmother used to recite poems that she'd memorized as a girl (this would have been the early 1900s, as she was born in 1892), and this is one I remember:

"Down in the pasture,
Carved on a rock,
Are these three words:
Forget Me Not."

Have no idea who wrote that or if I even have the words right, but I always think of it when I see these flowers. So unusual to find a truly blue flower, and when they grow in great patches as they do at my mom's house, they are striking. She was kind enough to give me another group of plants this year so I can attempt, AGAIN, to start my own shade garden of forget-me-nots. They seed themselves and then spread all over, so I'm hoping with these two years of plants going to seed under the deck steps, I should have my very own forget-me-nots going next year!
