Gelsemium sempervirens
Often the first blossoms to open in spring are the stunning, bright yellow, trumpet-shaped flowers of Carolina jessamine. This twining evergreen vine features dark green, glossy leaves that enhance the appearance of the abundant yellow blossoms. Carolina jessamine is a perennial native woody vine that can be found in remaining stands of native pine trees in The Woodlands. The yellow flowers are easy to spot in mid-to-late February among the green pine branches and other still dormant deciduous trees. When outdoors, look up to see the Carolina jessamine vines climbing into trees or hanging from branches. A glimpse of a few bright yellow flowers is a sign that spring is near!
A striking plant that deters wildlife, like deer, from eating its leaves and flowers due to toxins in the leaves and berries, Carolina jessamine has been valued in landscapes across southeastern United States for a long time. In the early history of our country, both George Washington and Thomas Jefferson directed their gardeners to plant Carolina jessamine on their property to beautify their homes. Thomas Jefferson shipped samples of the plant to England to serve as an example of the beautiful plants found in the New World. Carolina jessamine was even named the 2026 Wildflower of the Year by the Lady Bird Johnson Wildflower Center!

Despite its toxicity to humans and some wildlife, native bees, butterflies, and birds benefit from having Carolina jessamine in the landscape. The early spring flowers provide an important source of nectar when other plants are not yet blooming. Native bees, bumblebees, spicebush and tiger swallowtail butterflies enjoy the nectar of the fragrant yellow flowers. The fruit that forms later in the year provides food for warblers, grosbeaks, cardinals, mockingbirds, titmice, chickadees, and thrashers. Additionally, the mature vines provide cover for wildlife in their dense growth.
