In addition to the excellent choices you mentioned you are fortunate in
having as a native to those woods one of the most beautiful flowering trees,
the Flame Azalea (Rhododendron calendulaceum). Their blossoms are found in
shades of red, orange or yellow and they really 'light up' the woodland in
early spring. Other beauties I remember from the woods around Sewanee and
Chattanooga were wild violets, bluets (Houstonia or Hedyotis caerulea) and
lily-of-the-valley (Convallaria majalis). Also, where you could look down
upon the tops of the woods from above, the native wisteria (W. frutescens)
and the tulip poplar (Liriodendron tulipifera) were spectacular. Finally,
camellias and deciduous magnolias are wonderful plants for woodland gardens.
