I haven't tried to grow a catalpa from seed. However, the way that catalpa seedlings grow abundantly near mature trees I have observed--both in eastern and western Massachusetts--suggest they grow easily. My theory is that snow plowing has a lot to do with getting the beans buried and off to the sides of roads or parking lots, where they manage to grow without interference from lawn mowers or other controlled landscaping.
They can grow 12-18 metres (39-59 ft) tall
Catalpa speciosa
Catalpa ovata was created in 1837.
It is primarily an ornamental tree. The wood is too soft to use as lumber, but it is sometimes used in acoustic guitars. It is also used to attract and hold Catalpa Worms, which are used for fishing
