The specific epithet blanda means "charming". Similar but less common species include C. laxiflora and C. hitchcockiana. Carex laxiflora is more typical of mesophytic forests and is smooth on the angles of the bracteal sheaths. Carex hitchcockiana occurs in mesic woods and can be distinguished by its minutely pubescent sheaths.
