Gelsemium sempervirens, commonly known as yellow jasmine or evening trumpet flower, is a perennial vine native to the southeastern United States. It features bright yellow, tubular flowers that bloom in spring and early summer, attracting various pollinators. The plant typically grows in wooded areas and can reach lengths of up to 30 feet, often climbing on nearby structures or trees. This species is part of the Gelsemium genus and belongs to the Loganiaceae family. While it is admired for its ornamental beauty, all parts of the plant are toxic if ingested, containing alkaloids that can cause serious health issues.
