The American climbing trumpet ( Campsis radicans ) is one of the two species of the genus of the trumpet flowers ( Campsis ) within the family of the trumpet tree plants (Bignoniaceae). It is widespread in the central to eastern United States. Some varieties are used as ornamental plants .
description
Vegetative characteristics
The American climbing trumpet is a deciduous, woody liana . With the help of its adhesive roots, it grows very quickly and reaches heights of 5 to 10 meters, occasionally 12 meters or more. In the absence of support, the plant spreads on the ground, forming roots at the nodes of the branches and covering larger areas in a short time.
The opposite arranged leaves are divided into a petiole and a leaf blade. The leaves, which are up to 25 centimeters long, are light green at the beginning and later a strong medium green. They are pinnate unpaired and usually consist of seven to eleven leaflets, somewhat asymmetrical at the base, with serrated edges.
Generative characteristics
At the ends of the annual branches, clusters of flowers appear from July to September. The hermaphrodite flowers are weakly zygomorphic and five-fold with a double flower envelope . The five sepals are fused bell-shaped. The five petals are funnel-shaped, grown together like a trumpet and are 5 to 8 inches long. The palette of colors of the petals includes mainly orange to brick red tones; some varieties bloom yellow. There are only four curved stamens . The ovary is on top.
The capsule fruit contains many winged seeds.
ecology
In their homeland, the flowering plant is mainly visited by hummingbirds , which cause pollination by sucking nectar . Bees and bumblebees are the main sources of pollination outside the home area.
The capsule fruits require a lot of heat to ripen. When the capsule fruits pop open, the seeds are spread by the wind.

Taxonomy
It was first published in 1753 under the name ( Basionym ) Bignonia radicans by Carl von Linné in Species Plantarum , 2, pages 624-625. The new combination to Campsis radicans (L.) Seem. ex Bureau was created in 1864 by Berthold Carl Seemann in Louis Édouard Bureau : Monographie des Bignoniacées. 2e thesis 2 (Atlas) , page 16 published. Other synonyms for Campsis radicans (L.) Seem. ex Bureau are Campsis curtisii Seem. , Tecoma radicans (L.) Juss.
Use as an ornamental plant
It was introduced to Europe as an ornamental wood in the 17th century . The American climbing trumpet thrives in very warm, sunny to partially shaded locations on both sandy and loamy ground and does not have any special requirements for its pH value . It tolerates frost down to about −20 ° C. The varieties are mainly planted because of their decorative flowers for house greening on west and south walls as well as on walls.
Use in crafts and design
Around 1900, the New York company Tiffany used the colors and shapes of the leaves and flowers of the American climbing trumpet, in English: "Trumpet Creeper" when designing a floor lamp. One example of this lamp fetched US $ 794,500 at an auction held by Christie's New York auction house on December 8, 2009.
