I live here in Florida, enjoyed seeing the English ivy, wanted it and never knew that it is invasive here. I'm fighting thousands of tuberous thorny vines throughout my woods. They climb my trees, strangle them, break them and I assume they are native species (more than one species). I've dug out clusters of tubers that weighed 40-50 pounds. I wish they were good for something - maybe eating - because I sure have enough of them.
Given my problems with the thorny vines, I suspect I shouldn't add to my problems with vines. However, I wouldn't have known this except that it showed up here and I read it. It served a great purpose and I'm glad the conversation ensued. Please don't ban, just add the other side of the coin.
