This plant sprouted in our flower box after we removed the flowers that were previously there. It does not resemble the flowers that were removed, so it couldn't be that we didn't get it all or it reseeded. It may have grown there due to my in-laws randomly tossing in vegetable seeds to see if they will grow. In any case, no one recognizes this plant and it is getting taller by the day. The tallest nearly at 4 feet. Any help would be appreciated. T
