The genus was named after the English botanist William Vernon. In West and Central Africa, these plants are commonly known as Bitterleaf, Ewuro, Ndole, and Onugbu. They are popularly consumed as leaf vegetables in Cameroon. The leaves have a sweet and bitter taste. Vernonia calvoana is a key ingredient in the Cameroonian national dish of Ndole.

In Brazil, Vernonia condensata is traditionally used for its analgesic, anti-inflammatory, and other medicinal properties.

Vernonia species are also used as food plants by the larvae of certain Lepidoptera butterflies, including Coleophora vernoniaeella and Schinia regia.
