“spring could not be far off, that every passing day had to bring us closer to it, and that here in the natural Eden of the Smokies it would surely, at last, burst forth. For the Smokies are a very Eden. We were entering what botanists like to call “the finest mixed mesophytic forest in the world.” The Smokies harbor an astonishing range of plant life—over 1,500 types of wildflower, a thousand varieties of shrub, 530 mosses and lichen, 2,000 types of fungi. They are home to 130 native species of tree; the whole of Europe has just 85. They owe this lavish abundance to the deep, loamy soils of their sheltered valleys, known locally as coves; to their warm, moist climate (which produces the natural bluish haze from which they get their name); and above all to the happy accident of the Appalachians’ north—south orientation.”
