Summary
A spectacular display of fragrant, sunshine yellow flowers!
Gelsemium sempervirens 'Margarita', commonly known as Carolina Jessamine, is a hardier than average cultivar of Gelsemium that's been known to withstand exposure to temperatures as low as -20°F. Although officially rated for USDA hardiness zones 7-10, we know people who have had great success growing it in zone 6.
Carolina Jessamine is often described as a "well-mannered" and "restrained" climber, and for good reason! Despite its ability to climb so well, it rarely takes over trees or porches, and is easy to remove if you think its gone too far.
Gelsemium Margarita also functions beautifully as a low-maintenance and informal mounding groundcover, especially on areas such as steep banks where it's got room to sprawl out!
Butterflies, bees, and (especially) hummingbirds absolutely love this plant!
The flowers from Carolina Jessamine are perfect for use as freshly cut flowers!
Deer-resistant. Salt tolerant!
Care
Carolina Jessamine Care
All parts of Gelsemium sempervirens 'Margarita' are toxic, including the sap. Handle with care and wear gloves when working with this plant.
Full sun is best for Gelsemium sempervirens 'Margarita' and often produces the best flowers. Locations receiving partial sun are also considered acceptable; however, too little light will cause negative growth issues.
Fertilization is suggested, especially if soil is poor. Our slow release fertilizer is a great option. Spring fertilizations are best.
Do all heavy pruning in late winter or very early spring. Plant may be cut back almost completely (10"+ above ground level) at this time if desired for sizing. All pruning should be done using a clean tool to minimize the risk of diseases. Gelsemium sempervirens 'Margarita' blooms on both new wood and old wood, so pruning should attempt to maintain the cleanliness and shape of the vine by removing dead and nuisance growth. Avoid over-pruning.
Water regularly, especially after planting prior to establishment. Attempt to keep soil lightly moist, but not wet. Prefers rich, moist, well draining, slightly acidic soil. It's suggested to place 2"-3" of mulch under this plant to help retain a light degree of ground moisture.
Space plants 3' apart.
