Summary
Gelsemium sempervirens, commonly known as Evening Trumpetflower, is an evergreen perennial vine or shrub native to open woodlands, forest edges, and scrub areas in the Southeastern USA, extending into Central America in countries such as Guatemala and Honduras. It thrives in the warm climates of these regions, often climbing high into the forest canopy. This species can reach 3–6 m (10–20 ft) in height when supported by trees or other structures, with slender, wiry stems. The flowers, which appear in late winter to spring, are yellow, occasionally with an orange center, and trumpet-shaped, measuring 3 cm (1+1⁄4 in) in length and 2.5–3 cm (1–1+1⁄4 in) in diameter. They are highly fragrant and attract a variety of pollinators with their nectar.
Evening Trumpetflower is valued for its aromatic, showy flowers and is often used to adorn arbors, trellises, and walls, especially in warmer regions. It has received the Royal Horticultural Society’s Award of Garden Merit, indicating its excellence for garden use. While it can tolerate mild and coastal UK climates, it requires protection or greenhouse cultivation in colder areas. For optimal growth, it prefers a sheltered location with full sun to light shade, moderate watering, and well-drained soil. It is relatively low-maintenance but can be susceptible to pests like aphids and mealybugs. It is also toxic if ingested, so caution is advised when planting in areas accessible to pets and children.CC BY-SA 4.0
