These little flowers (Sedum) live up to their common name "Live Forevers." At least that's what my Mom called them.
We had rows of them that had overgrown the area down the sides of our front walk so we removed them last year. Sure enough, this little sweetie came back anyway to bloom for us this Fall.
Welcome back, little one. It's sweet to see you again. I'll move you to a safer place for next year.
