To multiply the trumpet tree (Catalpa) - That's how it works
Already since the 18th century, the originally from North America trumpet tree (Catalpa bignonioides - not to be confused with the similar-sounding angel trumpet!) Cultivated as an ornamental tree in Europe. The up to 18-meter-high, deciduous tree is mainly due to its up to 20 centimeters long leaves. It owes its name to the large, orchid-like flowers that dip the tree between June and July in a white sea of flowers. The quite straightforward trumpet tree is also very easy to replicate.

From the large flowers develop up to the autumn up to 40 centimeters long, bean-like fruit pods, which is why the trumpet tree by the way bears the nickname "bean tree". These remain on the tree until the following spring and mature only at this time. You can harvest the very fine seeds in it when the pods have turned brown. Seed the seeds in potting soil, cover them lightly and place the seed box in a light and warm place. Most of the small grains germinate within a few days.
Propagate trumpet tree over cuttings
However, not all trumpet trees form seeds. In this case, fruits will hang on the tree, but they will be empty. Incidentally, you have the best chance of getting seeds after a very warm and rather wet summer! Alternatively, the trumpet tree can also be propagated via cuttings. These cut you after flowering in late summer, with this year's shoots are best suited.
Winterize the cutting frost-free, but cool and cultivate it in the bucket for the first two years if possible.
Tips
Older trumpet trees very often self-descendants, which are rooted in the immediate vicinity of the mother plant. You should always remove these, but you can also cut them off and use them like propagating cuttings.
