Plant Profile: Aureolaria laevigata

Smooth false foxglove is a flowering plant that belongs to the Orobanchaceae family, commonly known as boomrape. Many species within this genus exhibit full or partial parasitism, typically attaching to the roots of host plants found in dry, moist woodlands and thickets. This particular plant is semi-parasitic, primarily targeting the roots of oak trees, and it displays a sprawling, semi-erect growth habit that can give it a vine-like appearance.

Indigenous to the eastern United States, its range extends from Pennsylvania down to Georgia, with additional occurrences as far west as Mississippi and northeast to Ohio. It thrives in its natural habitat of woody, mountainous areas, favoring partial sunlight, dry conditions, and sandy or rocky soils. While it can be found throughout North Carolina, it is particularly prevalent in the Piedmont and mountainous regions. The smooth false foxglove flourishes when planted near oak trees, which serve as ideal host plants due to its parasitic nature.

The plant features bright yellow flowers and glossy green leaves that may remind one of Gelsemium sempervirens; however, a distinguishing characteristic of Aureolaria laevigata is its square stems, in contrast to the round stems of Gelsemium.
