"In the South and East, some of the worst offenders... include several honeysuckle species, the Melaleuca paperbark tree, autumn olive, privet, multiflora rose, kudzu, lantana, buckthorn, oriental bittersweet, purple loosestrife, Japanese stiltgrass, Norway maple, burning bush, English ivy, Japanese knotweed, Bradford pear, empress tree, Japanese barberry, wisteria, and mile-a-minute weed. These and many more invasive plants were introduced to this country by well-meaning horticulturists looking for exciting new species to sell in the garden trade." — Douglas W.
