The late-winter blooms of Carolina jessamine (Gelsemium sempervirens) herald the onset of spring in the south. Gelsemium sempervirens is a very common plant in gardens of the U.S. South, because it is a fragrant, native, evergreen climbing vine that’s easy to grow and manage. The flowers pop in an intense and vivid yellow very early in spring. Their sunny faces bring color and warmth to the end of winter in the South.

Carolina jessamine is a classic twining vine, climbing by wrapping its mighty tendrils around a vertical support. If you want to cover a wall or large post wooden fence, you will need small threaded steel cable — between ⅛ inch and ¼ inch in diameter — anchored in the ground and attached to the wall or fence with eyelets. It does well twining around fences with small metal slats and climbing up arbors and lattices.

It’s less common to see Carolina jessamine as a ground cover, but it can be done. Use it as a ground cover where it can spread to create an evergreen mass up to 3 feet tall. Wildlife value. As one of the earliest bloomers, Carolina jessamine provides nectar for hummingbirds and the spicebush swallowtail butterfly. To bring more spicebush butterflies to your garden, pair this vine with spicebush shrubs, like Lindera benzoin.

There is some evidence that this vine’s flowers are toxic to the European honeybee (Apis mellifera), but they are useful to many other native bees and butterflies. If you are a beekeeper, be sure to plant your yard with many other palatable flowers for your honeybees and leave the Carolina jessamine to the native bees, butterflies and hummingbirds.

Lots of shoots on one plant will grow thicker while becoming established. Keep this vine well watered after transplanting and maintain soil moisture with 2 inches of mulch at the base of the plant.

Like many vines, Carolina jessamine is an opportunist that may grab onto nearby structures. Survey your planting site and take note of nearby trees or other structures that the vine may want to climb on. This vine will naturally climb into nearby treetops if left unchecked.

Prune the plant after it flowers every year to keep it tidy. With vines it is better to prune lightly every year instead of pruning heavily every other year. Train the vine to follow an arbor or a lattice by lightly securing the vine stems with gardener’s tape or strips of flexible fabric. If you use it as a ground cover, prune the perimeter of the plant’s spread to maintain a compact form and keep it away from other areas of the garden.
