Trumpet creeper vines are often used for facade greening due to their vigour, health and their exotic flowers as a way to conceal down pipes or to cover pergolas. Trumpet vines need space (a certain distance from a facade), strong climbing trellises and regular intensive pruning. Trumpet flowers are loved by bees! >>> List of available varieties.
(Trumpet creeper, trumpet vine. Latin: Campsis)
Plant in a warm, sunny, wind-protected location. The soil should be deep, humus-rich, with a good water supply. Shade at the base of the plant is beneficial. Distance between individual plants: 3 to 6 metres. Trumpet flowers need a lot of space outwards when cultivated on a facade, because of their long overhanging shoots. Chose from our available varieties in the overview.
A self-climber, usually cultivated on facades as a shapeable espalier, (only the Chinese grandiflora variety has almost no adhesive roots). A climbing aid is strongly recommended. On pergolas and the like you'll have overhanging/cascading shoots. We've included two botanical species (wild forms) in our assortment: 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 pinnate (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.
Trumpet flowers need a trellis to train them and to shape a trunk. Most can grow as self-climbers, but they can fall of the wall as the plant gets heavier. Below is a table with suitable trellis shapes for the trumpet vine. Formation and trunk development are similar to grapevine pruning techniques. Choose a trellis in the medium or Easy basic range, or even in the heavy / massive range.
