Gelsemium sempervirens ‘Margarita’ – Carolina Jessamine

General Information: This cold-hardy Jessamine variety features large trumpet-shaped, canary-yellow blossoms. Glossy, evergreen leaves contrast with the sturdy, honey-scented, buttery-yellow blossoms. The bloom period is somewhat short, but ‘Margarita’ will blossom twice, once in spring and again in summer. Perfect to blanket a trellis, arbor, pergola, or fence. Plant near a doorway or sitting area where you can enjoy the many cheerful blossoms and sweet fragrance. An excellent low-maintenance vine, which can also be trained as a shrub. Though much more common in landscaping in the Southeast, this variety will tolerate colder winters. ‘Margarita’ was selected for exceptional cold hardiness, to Zone 6 (-10°F).

Cultivation Details: Grows in a variety of conditions, somewhat drought tolerant once established. Growers in Zones 6 and 7a may consider keeping the plant indoors for the first winter to allow hardwood to develop. When selecting a site, growers in these Zones should provide the mature plant with protection from harsh winter winds. Especially well-suited for growth along south or west-facing walls. This compact and tidy selection grows up to 12 feet. The nectar is enjoyed by hummingbirds. No serious disease or insect problems. Deer resistant. For a full array of color, scent, and pollinator attraction, it is recommended to plant a variety of plants that bloom around the same time or during ‘Margarita’s’ non-flowering interval. Consider pairing with Coral Honeysuckle (Lonicera sempervirens), Limber Honeysuckle (Lonicera dioica), Arctic Kiwi (Actinidia kolomikta), Hardy Kiwi (Actinidia arguta), Ground Nut (Apios americana), or Yellow Passion Flower (Passiflora lutea). Note, this species is toxic to humans and livestock if ingested, and may cause skin irritation in sensitive individuals. Little evidence exists, but it has been reported that this plant’s nectar may be toxic to Honeybees and other non-native Bees if too much is consumed. Not recommended for beekeepers.

Growing Requirements: Plant in full sun to partial shade. Prefers moist, well-drained, moderately-fertile soils. Too much soil fertility will encourage leaf growth and discourage flowering. Consider amending with lawn clippings or leaf mulch. Tolerant of most soil types.

Fun Facts: Bumblebees and the occasional Honeybee are often eager to obtain this plant’s nectar, but are unable to fit inside the flowers. They will sit under the leaves and chew a hole through the flower base to get it.
