I have an Ivy type of plant that a neighbor long ago gave to me & I cannot kill it or get rid of it. It has taken over the flowerbed! Two yrs in a row, we even dug up the flowerbed & thought we got rid of all of the roots, but it came back with a vengeance! It spreads like wild fire. When you rub the leaves, it smells like an orange. We've even sprayed it will Roundup trying to kill it & had no luck! Wish to goodness I knew what it is called.
