I've long been intrigued by Paulownia (empress). Nice to see others share the same thought. Unfortunately its strength in this area is a weakness for adoption because its so highly invasive: http://www.ecosystemgardening.com/paulownia-princess-tree-on-most-hated-plants-list.html http://www.ecosystemgardening.com/paulownia-princess-tree-on... Bamboo might be another option. While it can be invasive I think it's much more manageable.
