The compact wood of Paulownia 
is said to be a favorite for mak- 
ing tea boxes in Japan, retaining the aroma of the tea well. 
Paulowina tomentosa is not hardy in the northern inte- 
rior where, if at all, it is seen usually in the form of strong 
large-leaved suckers from the persistent roots, but it is one 
of the conspicuous trees in front of the Smithsonian building 
in Washington, and has been used as a street tree as far 
north as Brooklyn near the coast. 
Minutely velvety. (Imperial tree). P. tomentosa.
