This selection of our native woods iris was discovered by mad plantsman, Don Shadow of Winchester, Tennessee. Iris 'Tennessee White' is a vigorous deer-resistant selection that quickly makes a 2' wide deciduous clump, topped just above the foliage in March (NC) with a wonderful display of small, white, thick-textured flowers...a treat for hummingbirds. Everyone who has tried it agrees it is probably the best white-flowered selection of Iris cristata on the market.
