The trumpet climber - also known as trumpet flower or trumpet morning glory - only shows its beautifully shaped, bright yellow, red or orange flowers quite late in the year, namely from late summer into autumn. The strong-growing plant can be grown both as a ground cover and as a climbing plant and grows about two to three meters each year. Propagation is very easy.
The trumpet vine reliably reproduces itself
Trumpet vine spreads very quickly
Actually, you don't need to worry too much about the propagation of the trumpet flower, because the very vigorous plant spreads very quickly with seeds and offshoots (and if you're not careful, also very extensively!). If you want to avoid this uncontrolled spread, you should remove the fruits before the seed ripens and regularly cut back the plant vigorously.
Propagation by cuttings
Propagation by cuttings usually works very well for controlled propagation. Green head cuttings are used for this.
- In summer (approx. July), cut off this year's shoot tips that are between eight and ten centimeters long.
- Remove the lower leaves.
- Plant the cutting in sand.
- Put a clear plastic bag over it.
- Put the pot in a warm place.
- Keep the sand moist but not too wet.
- As new leaves appear, the cover can be gradually removed.
Overwinter the cuttings in a greenhouse or in a cool room at around 10 to 12 °C. The young plant should not be planted out until next spring.
In addition, propagation by root cuttings or sinkers is also very possible.
Propagating trumpet flower by seed
If you want to propagate the trumpet vine with seeds (perhaps you have collected them yourself), we recommend a preculture in early spring, for example on the windowsill or in the greenhouse.
tips
If you want to avoid the uncontrolled spread of the trumpet flower through root suckers, it is best to plant the plant together with the plant pot (remove the soil first!) in the ground.
