Yellow Jessamine Gelsemium sempervirens

Carolina yellow jasmine (sometimes called false jasmine or Carolina jessamine) is a member of the family Gelsemiaceae. It is a vine native to the southern United States, Mexico, and Guatemala. Its name derives from the Italian name for jasmine, gelsomino, and the species name indicates that it is evergreen. It was named the state flower of South Carolina in 1924.

It is best grown in moist, organically rich, well-drained soils in full sun. Although it will tolerate light shade, best flowering and growth occur in sun. It tolerates wind and is moderately tolerant of salt, wet soil, or short periods of drought. Carolina jessamine has a modest growth rate until well-established. It may grow from 12 to 20 feet as a twining vine trained to an arbor or trellis after three to four growing seasons. If unsupported, it creates a bushy ground cover. Pruning, which is best done soon after it finishes flowering, is generally only needed for shape and training to its support.

Admired for its sweetly scented, canary-yellow flowers and glossy evergreen foliage, this vine really puts on a show from February to May, depending on the weather. The foliage generally bronzes in winter.

Carolina jessamine can be found in the wild in wooded areas and thickets growing up tree trunks. It can become weedy in disturbed areas and along roadsides. In cultivation, it is well suited for growing in vertical spaces like trellises, arbors, fences, planters, porch columns, and screens.
