Yellow jessamine

Description

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 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. Gelsemium sempervirens can grow to 3–6 m (10–20 ft) high when given suitable climbing support in trees, with thin stems. The leaves are evergreen, lanceolate, 5–10 cm (2–4 in) long and 1–1.5 cm (3⁄8–5⁄8 in) broad, and lustrous, dark green. The flowers are borne in clusters, the individual flowers yellow, sometimes with an orange center, trumpet-shaped, 3 cm (1+1⁄4 in) long and 2.5–3 cm (1–1+1⁄4 in) broad. Its flowers are strongly scented and produce nectar that attracts a range of pollinators. Some 19th century sources identified Gelsemium sempervirens as a folk remedy for various medical conditions.
