Scientific name

The Campsis ( Campsis ), also called climbing trumpets , Jasmin trumpets , podranea or trumpet winds called, are a genus within the family of the Bignoniaceae (Bignoniaceae) is. Because of their flowers, they are also used as ornamental plants grown (mainly varieties and hybrids of the two species).


Blossom in longitudinal section

Campsis species are deciduous, woody climbing plants that develop adherent roots . The opposite leaves are pinnate unpaired with usually seven to eleven leaflets , which have a serrated leaf margin.

Some flowers are grouped in tufted inflorescences. The large flowers are weakly zygomorphic. The five sepals are fused bell-shaped. The mostly orange-red colored petals are fused together like a funnel. There are only four curved stamens . They have an upper ovary and form capsule fruits with many winged, disc-shaped seeds.

Occurrence and systematics

The two species of the genus Campsis :

  • American climbing trumpet ( Campsis radicans (L.) Seem. Ex Bureau , Syn . : Bignonia radicans L. , Tecoma radicans Juss. ): It is native to the central and eastern United States.
  • Chinese climbing trumpet ( Campsis grandiflora (Thunb.) K.Schum. , Syn .: Bignonia grandiflora Thunb. , Tecoma grandiflora (Thunb.) Loisel. ): It is native to eastern China and Japan . Their number of chromosomes is 2n = 40.

The North American species was introduced to Europe as an ornamental wood as early as the 17th century.

As an ornamental plant is now often also the Great trumpet vine ( Campsis x tagliabuana (Vis.) Rehder ), a cross between two species cultivated (indeed this is a whole group of hybrids , some of which differ greatly in climbing behavior and resistance to frost).
