RANGE: Virginia; naturalized in our gardens. 



USES. A mild and resolutive oil is extracted from the seeds, but when eaten they 

 have a very sharp taste. In former times nuns used them to make rosary beads. These two 

 small trees can add variety in parks and they're already quite widespread. 



Cultivation. They're propagated from their shoots, which are plentiful. 

 Autumn is the best season to transplant them. They're very hardy and thrive in all sorts of 

 soils and exposures.
