This plant blew into the garden from somewhere a few years ago and is now well established. It appears to be a member of the Persicaria family, probably P. maculosa, “Lady’s Thumb,” a member of the knotweed family.
Some sources report that P. maculosa produces a yellow/green dye (with an alum mordant), although one source says red/brown.
Cheery yellow bloom.
