Stachytarpheta is a plant genus in the verbena family (Verbenaceae). The flowers are rich in nectar and popular with many butterflies, such as the South Asian crimson rose, Malabar banded swallowtail, and grass yellow. Hummingbirds, especially small species like Lophornis coquettes, Chlorostilbon emeralds, and Discosura thorntails, are especially attracted for nectar. Several species in this genus are known as porterweeds. In Australia the genus is known as snakeweed.
