Asiatic Bellflower Wahlenbergia marginata

Other Common Name(s):

Previously known as:

  • Campanula agrestis
  • Campanula indica
  • Campanula marginata
Description

Southern rockbell is an herbaceous perennial native to Asia in the Campanulaceae family.   The species name marginata means  "marg(in)" in Latin or  "border, edge" signifying where plant grows as it is commonly found along roadsides and disturbed areas. 
The genus Wahlenbergia from the Swedish Naturalist who discovered the plant Goran (George) Wahlenberg (1780-1851).   

It is used in its native countries to treat skin eruptions.  

In its native habitat, it can be found growing in wastelands, fields, slopes and streams as well as those noted above.  It has become naturalized in the United States. In North Carolina, it has been identified in the Sandhills and southern Coastal Plains, however, its range is spreading to other areas.  Locations where it becomes established include dry or sandy roadsides, fields, fallow fields, and as a yard weed. The habitat can include a single plant, to a stand of hundreds.  Due to the plants small size, it is difficult to locate.  Without the flowers blooming, it is easily overlooked.
