Gelsemium sempervirens

Gelsemium sempervirens is a twining vine in the family Gelsemiaceae, native to subtropical and tropical America: Honduras, Guatemala, Belize, Mexico (Chiapas, Oaxaca, Veracruz, Puebla, Hidalgo), and southeastern and south-central United States (from Texas to Virginia). It has a number of common names including yellow jessamine or confederate jessamine or jasmine, Carolina jasmine or jessamine, evening trumpetflower, gelsemium and woodbine.

Yellow jessamine is the state flower of South Carolina.

Despite its common name, the species is not a "true jasmine" and not of the genus Jasminum.
