American climbing trumpet is hardy - other species are not
The climbing trumpet or trumpet flower (Campsis) impresses with its lush growth and the large flowers in rich colors. The plant needs sun and a nutrient-rich soil, otherwise it is quite easy to maintain. However, not all species and varieties of climbing trumpet are hardy.
Hardiness depends on species and species
Basically, three different types of climbing trumpet are distinguished, with only the American climbing trumpet (Campsis radicans) and the Great climbing trumpet (Campsis tagliabuana), a hybrid, for temperatures between - depending on the variety - minus 15 ° C and minus 20 ° C hardy. Much more sensitive and therefore not hardy is the Chinese climbing trumpet (Campsis grandiflora), which is also not suitable for planting in the garden.
Winterhardt trumpet flowers
In the table below we have put together some hardy climbing trumpet varieties for you.
Overwinter the climbing trumpet
With the exception of young, not yet lumbered climbing trumpets and the not hardy Chinese climbing trumpet you can easily overwinter trumpet flowers in the open air. It is important that the plants have a protected location and are protected by a foliage and / or brushed layer from very cold temperatures. Young climber trumpets develop their cold resistance only with age - the more woody, the less sensitive they are. On the other hand, Chinese climbing trumpets should be kept in a cool, but frost-free place under cold conditions - a winter in the heated living room is not recommended, temperatures between 10 to 12 ° C and a bright spot are ideal.
Tips
Do not be surprised if your trumpet flower does not seem to drift off in the spring: the first leaves come late after the winter break, usually only in May.
