Question
Can you tell me where I can purchase a catava tree in the Houston Texas area?  I am looking to plant for the worms for fishing just like everyone else - thank you.

Answer
Catalpa Tree [Catalpa bignonioides] sometimes called Catawba tree.

I do not know of a nursery in the Houston area. I would suggest either calling a few or here is a tree nursery in Ga that will ship the trees. Here is the web link to their prices.  http://www.tytyga.com/product/Catalpa+Tree
