Campsis radicans (also known as Trumpet Vine and Trumpet Creeper) is a fast-growing, woody vine that produces clusters of vibrant trumpet-shaped flowers and can grow up to forty feet (12 m) tall.
It is native to the southeastern region of the United States and attracts hummingbirds.
The Trumpet Vine produces pinnate compound leaves that are four to twelve inches (10 – 30 cm) long, covering the vine with bright green foliage.
The leaves have seven to eleven oval leaflets with serrated edges and are one to four inches (2 – 10 cm) long, and ½ to 1 ½ inches (1 – 3 cm) wide.
The vibrant, trumpet-shaped flowers are orange, red, or yellow in color. Flower clusters first bloom in early spring to summer, and are produced continually until early autumn. The tubular flower buds are three to four inches (7-10 cm) long.
As trumpet flowers fade, they are replaced by seed capsules, which are four to eight inches (10-20 cm) long, and hang on the vine through the winter. Aerial roots run along the stems and attach themselves tightly to surfaces.
Campsis radicans is a fast growing vine that requires some type of support, such as a trellis, fence, or pole. Avoid structures due to the adhesive substance (which can ruin paint surfaces) that the aerial roots use to cement themselves to surfaces.
USDA Hardiness Zone
USDA Zone 4 - 10
Full sun to partial shade.
During the first growing season, keep the soil moist to a one inch depth. In absence of rain, supplemental watering once a week may be required.
Once established, needs only occasional
Apply a balanced fertilizer in the early spring and then again six to eight weeks later.
Trumpet Creeper can be propagated from division, seeds, and stem cuttings. The best time to propagate is in the fall or spring. Allow pods to dry on the vine, and then break open the pods to collect seeds.
Prefers rich, well-draining soil.
Campsis radicans will quickly cover trellises, fences and other supports. Prune as needed to control size. The best time to prune is in the summer after flowering; however, additional pruning may be necessary to control vigorous growth.
