A sural nerve biopsy may be useful to enable the clinician to diagnose the etiology and underlying pathology of patients presenting with symptoms of a peripheral neuropathy, when no clear underlying cause has been determined with conventional assessment such as electrophysiology or quantitative sensory testing.
The Best Wildflower Hikes in the Great Smoky Mountains The Great Smoky Mountains are home to more than 1600 species of flowering plants. During each month of the year, some forb, tree or vine is blooming in the Smokies. During the spring, wildflowers explode during the brief window just prior to trees leafing out and shading the forest floor (from about mid-April thru mid-May).
Deadheading strengthens bulbs because they won't try to produce seed. Daffodils (Narcissus spp.) provide spring flowers, while lilies (Lilium spp.) bloom most profusely during summer. Most daffodils grow in U.S. Department of Agriculture plant hardiness zones 4 to 11, depending on the variety, while lilies thrive in USDA zones 3 to 8.
