There isn't many around, but I did find one that is growing up on what appears to be a white pine seedling. Thanks all for pursuing this thread. I'm certainly not on a witch hunt for invasive plants. It's just the opposite. I want to protect as much diversity as I can on our property. We do have many plants that, in many regions, are considered invasive, but we control them and enjoy them. I posted a similar inquiry about a beautiful plant that turns out to be a Japanese knotweed and was told that I have "one chance to kill it." Just wanted to make sure this was not in the same category.
