Carolina Jessamine, also known as Gelsemium sempervirens, is a flowering vine native to the southeastern United States. It features bright yellow, trumpet-shaped flowers that bloom in the spring and early summer. The plant can grow up to 20 feet long and is often used for ornamental purposes in gardens and landscapes. This vine thrives in well-drained soil and prefers full sun to partial shade. While it is admired for its beauty, all parts of the plant are toxic if ingested, containing alkaloids that can be harmful to humans and animals. Care should be taken when planting it in areas accessible to pets and children.
