Carolina Jessamine (Gelsemium sempervirens) is a fast-growing, evergreen vine native to the southeastern U.S., including Texas. Despite its common name, it is not a true jasmine, those being in the Jasminum species. It produces bright yellow, trumpet-shaped flowers in late winter, adding vibrant color to fences, trellises, and arbors. This vine is highly adaptable, tolerating both acidic and alkaline soils, as well as periods of drought once established. It prefers well-draining soil but can handle occasional wet conditions.

This plant is an excellent choice for Texas landscapes due to its heat and cold tolerance. It remains evergreen in milder winters but may lose some foliage in colder regions. While deer generally avoid it, it is important to note that all parts of Gelsemium sempervirens are toxic if ingested, making it unsuitable for areas where livestock or curious pets might graze.

Mature plants reach 10-20 feet long and can spread 3-6 feet wide, depending on support structures. When planting multiple vines, spacing 4-6 feet apart is recommended. Carolina Jessamine is a low-maintenance option that provides year-round interest with its glossy foliage and seasonal floral display.
