Attached is a photo of a plant that appeared in my landscape bed this spring. It sprouted in a location where I had sown a package of mixed wildflower seeds, but no wildflower sprouted - except maybe this one. Otherwise, I don't know where it may have come from unless is a native weed of some type. Can you identify it?

That's a native weed in the Rumex genus. I never can figure out which species I'm looking at but I'm guessing you have Curly Dock.

Curly Dock (Rumex crispus)

Or Red-veined Dock (Rumex sanguineus var. sanguineus)

That's what I always called it.
