Paulownias long have held mythical, spiritual, cultural, and economic significance in China and Japan (Hu S. Y. 1959, 1961). The wood of some species is highly prized in Asia; Paulownia tomentosa is grown in the United States in plantations for wood that is exported to Japan.
The fossil record provides evidence of Paulownia in North America and Europe during the Tertiary (C. J. Smiley 1961).
