Crownbeard is the common name of Verbesina, a genus of flowering plants, in the daisy family (Asteraceae). They bear yellow flowers similar to small sunflowers. The name Verbesina refers to the similarity of the foliage to that of the (unrelated) verbena.
Verbesina species are used as food plants by the larvae of some Lepidoptera species. These include Schinia bina, which has been recorded from V. encelioides, and Schinia siren which feeds exclusively on that species.
Actinomeris is a basionym of Verbesina.
