Mountain Meadow-rue

Thalictrum clavatum is endemic to the South and Central Appalachian regions of the United States, namely the states of Virginia, West Virginia, North Carolina, South Carolina, Georgia, Kentucky, Tennessee, and Alabama. While it is abundant in the mountainous regions of Appalachia, it has also been sparingly reported in Western Piedmont Foothill regions at low elevations. Thalictrum clavatum is characteristically found in dense forests nearby cold water sources, namely wooded seepages, streamsides, spray cliffs at waterfalls, and brookbanks. While the plant species is commonly observed in groves, stands, leaks, screes, and outcrops, among other wooded and riparian environments, in less frequent instances, it has been reported in rich cove forests. Thalictrum clavatum can be observed at elevations ranging between 0 – 700 feet; however, it is most often found at elevations of 500 feet. Thalictrum clavatum is labeled as L48 N within the Natural Resource Conservation Services sector of the United States Department of Agriculture, signifying that it is a native species of the continental United States. Thalictrum clavatum has a heliophily value of three. The Heliophyte Index measures the degree to which a species requires sunlight for growth and reproductive success. …
