Lonicera sempervirens, or trumpet honeysuckle, is a vigorous, deciduous, climbing vine that usually grows 10-15 feet (occasionally up to 20 feet) and is one of the most attractive vining honeysuckles. It is mainly found in the southeastern United States.
The vine produces large, non-fragrant, narrow, trumpet-shaped flowers that are scarlet to orangish red on the outside and yellowish inside. The flowers bloom in late spring at the ends of the stems in whorled clusters. They are appealing to hummingbirds, butterflies, and bees. The vine also produces inedible red berries that can be ornamental from late summer to early fall, attracting birds. The oval, bluish-green leaves are glaucous underneath. In warmer winter climates of the Deep South, this vine remains evergreen.
It thrives in average, moderately moist, well-drained soils in full sun. While it can tolerate shade, its best flowering occurs in full sun. It prefers humus-rich, organically fertile soils with good drainage. This climbing vine requires a support structure to grow unless it is allowed to spread as a ground cover. Prune as necessary immediately after flowering.
