    Looks like Pennsylvania smartweed to me, also. Usually grows taller in shrub beds and flowers. Has the red flowers and seeds at this time of year.

    I agree. I have that on the edges of the rows in my orchard. Glyphosate and T-zone will not kill it. T- zone by itself works better.

    Easy to just pull out when I see one.

    If I saw it around here I'd think it was knotweed. But I am not familiar with PSW.

    You wouldn't say that if you ever tried to eradicate it.

    if its smart weed it dies pretty easy, it hard to tell by the photo it gets steamy this time of the year.
