Campsis radicans is native to the southeastern and Gulf Coast region of the United States where it grows along fences and at the edge of woodlands. Campsis radicans are also known as Trumpet Creeper or Trumpet Vines.
Characteristics of Campsis Radicans
- The trumpet creeper is a fast growing, high climbing deciduous woody vine that will grow to heights up to 40 ft (12.2 m).
- It has large trumpet shaped flowers that are bright red to orange on the outside, yellow inside and grow in clusters of 2 to 9 Flowers.
- Flowers are followed by long, bean-like seed pods (3-5″ long) which split open when ripe releasing numerous 2-winged seeds for dispersal by the wind.
- It’s flowers attract hummingbirds and provides valuable cover for birds and small mammals.
- The vine’s aerial roots that occur along the stems that attach tightly to surfaces. Once the vine climbs to a certain height it grows horizontal branches that reach away from the support in a quest for light and space.
How to grow Campsis Radicans
- It prefers rich moist soil but is adaptable to less than optimal situations.
- Use a loose, sprawling groundcover, to cascade over a rock wall, as a point of interest on a single fence post, or as a spectacular sweep up the side of a stone building.
- They should be planted where it’s spread will not be a problem or can be controlled by mowing as they grow very fast.
- Prefers full sun for maximum growth and flower production, but tolerates partial shade.
- Showy clusters of yellow orange to red trumpet-shaped flowers first appear in summer (earlier in frostfree climates) and are produced continuously until early autumn.
Usage of Campsis Radicans
- It is best used in woodland gardens and natural areas where it has space to grow.
- It covers fences and other structures.
- It’s easy to grow trumpet creeper on arbors but remember that the aerial roots use a powerful adhesive substance to cement themselves to supports which almost certain to ruin paint surfaces.
