Carolina jessamine (Gelsemium sempervirens) is a twining vine with dense clusters of yellow tubular flowers with shiny evergreen leaves.
Currently in bloom in many parts of the Southeastern United States, the fragrant flowers depend on various bees (bumblebees, carpenter bees, and blueberry bees) for cross-pollination in order for fruits and seeds to mature.
Look for it along forest edges, roadsides margins, and on rock outcrops.
It's also a popular landscape plant due to its colorful long-lasting flowers, shiny evergreen leaves, and its ability to tolerate drought.
Carolina jessamine is the state flower of South Carolina.
