Hybrid catalpa is the result of a cross between the Chinese catalpa and the native southern catalpa. Like other catalpas, this tree has showy white flowers in spring, followed by bean-like seed pods. This hybrid may be difficult to find in nurseries. When it is sold, it is often the cultivar ‘Purpurea’ that is available.
