 B. prcecox) is usually a biennial, the young plants becom-

 the young plants are ready for use the following spring; 

 or seeds may be sown in earliest spring. The plant is 

 perfectly hardy and it is common in the natural state 

 over a large part of the United States. Although a com- 

 mon plant, it is little known in general cultivation either 

 in this country or abroad.
