Rank Reasons
Cardamine flagellifera is endemic to the Southern Appalachians of North Carolina, South Carolina, Tennessee, Georgia, Virginia, and West Virginia. It has moderate threats, and is not common anywhere within its range. Populations are most numerous in Georgia and North Carolina.
Range Extent Comments
Cardamine flagellifera is nearly endemic to the Southern Appalachians of western North Carolina, South Carolina, east Tennessee, northeast Georgia, western Virginia, and southern West Virginia (NatureServe Natural Heritage Network Database 2018, Weakley 2015). This plant also occurs disjunct in the Cumberland Plateau of Tennessee (Beck and Van Horn 2007, NatureServe Natural Heritage Network Database 2018).
Occurrences Comments
Cardamine flagellifera is not common anywhere within its range. Populations are most numerous in northeast Georgia and western North Carolina.
Threat Impact Comments
Feral hog rooting and in some cases deer browsing are threats (Rock 2000). Loss of habitat, and some forest management practices are moderate threats (Southern Appalachian Species Viability Project 2002).
Ecology & Habitat

Habitat

Cardamine flagellifera occurs in seeps, on streambanks, bottomland forests and in moist cove forests at moderate to lower elevations in the Southern Appalachians (Poindexter 2013, Weakley 2015). In southwest Virginia it occurs in rocky seepages (Weakley et al. 2012). In the Cumberland Plateau of Tennessee it has been found on deciduous forested slopes (Beck and Van Horn 2007).
