The Catalpa beans are not edible, but have several uses. Indians used many parts of the tree for medicines and some say they can be used to keep moles out of a yard.
They are fairly woody/bark-like in texture when dry.
The scientific name for the Northern Catalpa is Catalpa speciosa.
Many in my region (western Ky.) use the beans in their yards to kill grub worms as to ward off moles in our yards. Works pretty good.
Of course you can smoke it! I have found that the effects are better though if you let the dried beans soak in a bowl with some apple cider vinegar until it evaporates and dries the bean back out. Don't forget to break the bean into 3 or 4 1 1/2 or 2 inch pieces before soaking. Cut it up fine after the soak, and enjoy the nice smooth flavor!
Catalpa speciosa
the Northern Catalpa
Catalpa ovata was created in 1837.
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.
Most types of Catalpa are deciduous. None are coniferous.
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
