Carolina Jessamine (Gelsemium sempervirens): Native Vine for Early Spring Color

Carolina jessamine (often misspelled "jasmine") is a southeastern US native vine prized for fragrant yellow trumpets heralding spring. Vigorous but manageable with proper siting.

Identification & Growth Habit

• Evergreen vine: Glossy, rich green leaves (2–3″).
• Flowers: 1–1.5″ yellow trumpets, sweet fragrance. Late winter → early spring (Feb–Apr).
• Size: 10–20 ft with support. Compact in sun; sprawling in shade.
• Native range: VA to FL, west to TX, Mexico. Streams, lowlands, woodland edges.

Culture & Care

• Light: Full sun to part shade. Best bloom in sun; foliage denser.
• Soil: Moist, well-drained, adaptable. Not wet-tolerant.
• Water: Regular first year. Established: drought-tolerant but prefers consistent moisture.
• Support: Trellis, arbor, fence, tree. Twines clockwise.
• Container option: Restricts vigor; use large pot + trellis.

Critical Considerations

• TOXICITY: All parts contain gelsemine alkaloids. Fatal if ingested. Keep from children/pets. Wear gloves; wash after handling. Sap irritates skin.
• Aggressive spread: Can smother weak plants. Site away from delicate specimens. Root barrier if near beds.
• Pruning: After bloom. Can cut hard to rejuvenate.

Landscape Uses

• Arbor/pergola cover (fragrant entrance).
• Fence screening (evergreen).
• Woodland edge naturalizing.
• Container specimen (patio fragrance).

Wildlife Value

• Early nectar for bees, butterflies, hummingbirds.
• Deer resistant (toxic).
• Host for some Lepidoptera.

Carolina jessamine delivers reliable, fragrant early color with native ecology benefits—just respect its toxicity and vigor.
