Eastern smooth beardtongue, a native species of North Carolina belonging to the Scrophulariaceae family, is a herbaceous perennial that typically reaches heights of 2 to 3 feet. Its leaves are arranged oppositely, featuring a slightly serrated edge and a hairy underside. The lower leaves are characterized by long stems, while the upper leaves have shorter stems. This plant thrives in woodlands and open fields, favoring rich, moist soils and full sunlight. The lance-shaped leaves measure between 2 to 4 inches in length and are stalkless. From May to July, it produces clusters of purplish-white flowers at the upper sections of its stems. These blooms are tubular and asymmetrical, with a hairy lower lip, which is the origin of its common name, beardtongue. Known for its ease of cultivation, this plant requires moderate watering and minimal maintenance, making it an ideal choice for rock gardens, butterfly gardens, or cottage gardens.
