PODCAST: Researchers at the University of Minnesota in Duluth recently unveiled a new kind of tree after 20 years of research. It is a cottonwood-poplar hybrid that can grow up to eight feet per year, which is remarkably fast. That means it could be taller than a two-story house in just a few years. The scientists behind the new tree see it as a possible quick solution to getting shade in residential areas and removing toxins from soil. Jeff Jackson is a University of Minnesota extension educator who has been working on the new tree. He joined Minnesota Now to talk about how the new “InnovaTree” could shape the future.
