In its North American homeland, the trumpet tree is a widespread ornamental tree that can be found in many gardens and public parks because of its foliage and flower decoration - although the ball trumpet tree develops rather few flowers in contrast to its larger relative. However, all parts of Catalpa bignonioides, the botanical name of the tree, are considered to be slightly poisonous for both humans and animals.

With the exception of the seeds, all parts of the globe trumpet tree contain the mildly toxic catalpin, a compound also said to repel mosquitoes. The leaves of the tree in particular exude a light scent that keeps the annoying pests at bay. Other components that are also only slightly toxic are caffeic acid, ursolic acid and coumaric acid. In addition, quinoid compounds have been found in the wood, which can lead to allergic reactions. For this reason, you should always wear gloves when pruning the ball trumpet tree.
