Campsis Radicans – Vibrant Trumpet-Shaped Flowers
(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
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)
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
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 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 watering.
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.
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.

How to Propagate Campsis radicans
Select several semi-hardwood cuttings from a healthy, mature trumpet
- Take four to six inch cuttings from the tips of the vine's
lateral stems. Each cutting should have a minimum of four sets of
- Trim the leaves in half and place the cuttings in water
while you prepare the rooting pots.
- Combine equal parts of horticultural sand and compost. Fill
a two gallon pot with the mixture. Water it to a depth of six inches.
- Insert the cuttings into the soil. Bury one-half of their
length in the soil. Plant the cuttings two inches apart.
- Place a clear plastic bag over the top of the pot. Place
the pot in a bright location away from direct sunlight. Temperature
should remain above 50° F.
- Water the soil to a depth of four inches every two days. Do
not allow potting soil to dry out.
- Plant the trumpet vine cuttings outdoors in a sunny
location after the last frost of the following spring.
