    I have what I thought was a Foxglove plant grown from seed in my border and have 2 questions:

    1. Does this look like a Foxglove?
    2. More importantly what are the black marks on every leaf?

    Hope you can shed light on this, thanks.

      Certainly one of the Persicaria tribe.

        Yes it's knotweed, the black markings are one of it's traits.
