Safety Overview
1.Yellow Jasmine — Overview
Yellow Jasmine (Gelsemium sempervirens) is also widely known as Carolina Jasmine. It is an enchanting evergreen climbing vine in the Gelsemiaceae family. It is native to the southeastern United States, ranging from Virginia to Florida and extending into Mexico. The plant is a prominent feature of its natural habitat. Morphologically, slender, twining stems characterize it.
Glossy, lance-shaped leaves adorn these stems and stay vibrant throughout the year. Its most striking feature is the profusion of bright, trumpet-shaped, fragrant yellow flowers. These typically bloom in late winter to early spring, signaling the arrival of warmer weather. Its appearance and scent are alluring. However, one fact is crucial to note.
Gelsemium sempervirens is a 'false jasmine,' unrelated to the edible true jasmine varieties used in teas. It thrives in well-drained soils and prefers ample sunlight. It is often seen gracefully climbing fences, trellises, or trees in its native range. The plant's roots and rhizomes are particularly significant because of their potent phytochemical composition. This composition has drawn both historical interest and modern scientific scrutiny for its powerful, yet highly toxic, medicinal properties.
