A yellow flowering plant, the Carolina jasmine (Gelsemium sempervirens), a common ornamental vine in the southern United States.
Possibly derived from Arabic 'yasamin' (jasmine) combined with a Romance language ending, though the exact etymology is uncertain and may reflect historical confusion with actual jasmine plants.
Gessamine isn't actually a jasmine at all—it's a classic case of colonial botanical confusion where European settlers mistakenly named plants after ones they knew back home.
