Paulownia (Paulownia tomentosa), or kiri, was introduced into the US during the 1800s. It quickly became naturalized over much of the eastern states. Except for its ornamental qualities, it was generally ignored or considered a weed tree. However, since Japanese buyers have begun to buy US grown logs, Paulownia is now considered a premier timber species. Prices paid for Paulownia logs often exceed those paid for black walnut, recognized as "The King" of the hardwoods. This publication contains specific information for the paulownia grower on site selection, seed collection and storage, planting stock development and early plantation care. A recent publication from the University of Kentucky, Department of Forestry, "Paulownia Plantation Management: A Guide to Density Control and Financial Alternatives" gives specific information on spacing and growth characteristics necessary for the production of high quality logs.
