Estimated Native Range
Summary
Gelsemium rankinii, commonly known as Rankin’s Trumpetflower, is a semi-deciduous perennial vine native to the coastal plains, woodlands, and scrublands of the Southeastern United States. It can climb to heights of 15-20 feet (5-6 meters) with a spread of 10-15 feet (3-4.6 meters). This vine is characterized by its twining habit and lanceolate leaves. It produces showy, funnel-shaped yellow flowers that are particularly abundant in the spring and sporadically bloom in the fall, attracting pollinators such as bees and butterflies.
Rankin’s Trumpetflower is valued for its ornamental flowers and ability to cover structures quickly, making it suitable for trellises, fences, and as a natural screen. It is relatively low-maintenance, requiring only occasional pruning to control its spread. In cultivation, it thrives in full sun to part shade and prefers well-drained soils, though it can tolerate a range of soil types. While generally pest-free, it can be susceptible to aphids and mealybugs. Gardeners should be cautious as all parts of the plant are toxic if ingested.CC BY-SA 4.0
