The Trumpet vine or Trumpet creeper (Campsis radicans), also known as "Cow itch vine," is a large and vigorous woody vine of the family Bignoniaceae, notable for its showy trumpet-shaped flowers. It is native to woodlands of the southeastern United States, but popular for arbors across the warmer parts of the country.

The leaves are ovate, pinnate, 3-10 cm long, and emerald green when new, maturing into a dark green. The flowers come in terminal cymes of 4-12, orange to red in color with a yellowish throat, and generally appear after several months of warm weather. The plant as a whole may grow to 10 meters in height.

The flowers are very attractive to hummingbirds, and many types of birds like to nest in the dense foliage.

It grows well on arbors, fences, and trees, although it may dismember them in the process. Ruthless pruning is recommended.
