Catalpa ovata from China, with pale yellow flowers, is also planted outside its natural range for ornamental purposes.
There is also a "pale" phase where the black striping is not as prevalent or missing altogether and a shade of white has replaced it. They grow to a length of about 5 cm (2.0 in) and feed on the leaves of the northern catalpa and, more commonly, the southern catalpa, also known as catawba or Indian bean trees.
