Family:

Wood Betony is a perennial herbaceous plant belonging to the broomrape family, indigenous to southeastern Canada, the southeastern United States, and eastern Mexico. In North Carolina, it can be found throughout the state, although it is uncommon in coastal plain regions. This plant thrives in diverse environments, such as open woodlands, thickets, and clearings. As a hemiparasite, Wood Betony attaches to the roots of various plants, including certain grasses, while also being capable of photosynthesis due to its own chlorophyll production.

The foliage primarily forms a basal rosette, accompanied by a few leaves along the stem. Its lobed, wavy-edged leaves give it a somewhat fern-like appearance. From April to June, a spike of two-lipped yellow flowers emerges, blooming sequentially from the bottom upwards, which attracts bees.

Wood Betony favors moderately well-drained soils and can grow in full sun to partial shade. It is well-suited for use in naturalized settings, open woodlands, or native plant gardens.
