Information on the trumpet creeper vine

Trumpet creeper vines are often used for facade greening due to their vigor, health and their exotic flowers, for example as a way to conceal down pipes or to grow on pergolas. Trumpet vines need space, especially away from the wall, strong climbing trellises and regular drastic pruning. Trumpet flowers are appreciated by bees! >>> List of available varieties.

(Trumpet creeper, trumpet vine. Latin: Campsis)

Campsis, from left to right: "Flamenco", "Stromboli" and "Indian Summer"

Requirements / Price

The planting location should be warm, protected from wind and sunny. The soil should be deep, humus rich with a good water supply. Shade on the foot of the plant is beneficial. Distance between individual plants: 3 to 6 meters. Trumpet flowers need a lot of space outwards when cultivated on a facade, because of their long overhanging shoots. Chose among available varieties in the overview.

Caracteristics and Pruning

"Self-Climber', (only 'Grandiflora' has almost no adhesive roots. Usually cultivated on facades as woody climbing plant, a climbing aid is strongly recommended. On pergolas the shoots will hang over. There are two botanical species (wild forms): Campsis radicans is originally from North America and was introduced in Europe in 1622 (frost resistant). Campsis grandiflora is originally from China. There are many crosses and varieties which differ in flower density, climbing behaviour and winter hardiness.

All trumpet flowers have feathered leaves that last from May to October with a beautiful yellow autumn colour. Most varieties show red, sometimes also orange and yellow flower umbels from July to September. The flowers are "rainproof" and fall off by themselves. Some inexpensive untreated plants will only bloom after several years. The fruits are pod-like capsules. No pruning in summer as the flowers appear at the extremities of the young shoots! "Winter" pruning is done in March, with all (side) shoots cut down to approx. 4 -10 cm long spurs, similar to the grapevine pruning technique.

Wire rope trellis

Trumpet flowers need a trellis to train them and to shape a trunk. Most can grow as self-climbers, but they might fall of the wall as the plant gets heavier. There is a table with suitable trellis shapes for the Trumpet vine. Formation and trunk development are similar to grapevine pruning techniques. Chose a trellis in the Medium or Simple "Basic"range, or even in the heavy / massive range.
