The spherical trumpet tree (Catalpa bignonioides) is created by grafting onto a conventional trumpet tree and stands out due to its naturally spherical crown. The very large, heart-shaped leaves only sprout very late, but they are an enchanting eye-catcher in the garden. On the other hand, the tree blooms little or not at all.
When and to what extent does the ball trumpet tree bloom?
The globe trumpet tree (Catalpa bignonioides) flowers rarely or not at all, although the few white flowers can appear in June and July. This tree is mainly cultivated for its decorative foliage, not for its flowers.
Ball trumpet tree is cultivated primarily for its leaves
The few white flowers of the globe trumpet tree appear in the months of June to July, although the flowers may fail from time to time. This develops into bean-shaped fruit capsules up to 40 centimeters long, which remain on the tree over the winter and do not open until the next spring. However, the ball trumpet tree is cultivated primarily for its decorative leaf decorations. The leaves, which sprout late and are reminiscent of elephant ears, turn a beautiful yellow in autumn and are shed before the first frost.
Tip
In contrast to the trumpet tree, the ball trumpet tree cannot be propagated by seeds, suckers or cuttings, but only by grafting.
