Introduced Plants in Northeast Tennessee

Anyone who botanizes in Tennessee’s five most northeastern counties, Carter, Johnson, Sullivan, Unicoi, and Washington, must surely be impressed with the large number of foreign species that have made themselves at home in this area. And I feel quite sure that the same holds true for the other Tennessee counties adjacent to this area as well as to those of North Carolina and Virginia that are also adjacent to this part of Tennessee. Some have become more or less serious pests. The Japanese honeysuckle (Lonicera japonica Thunb), at one time in good repute, has especially become a very serious pest, not only here, but over much of the United States.
