HELIAN'THUS continued. 



Sunflowers are quite hardy and are no trouble to 

 grow, and for newly-made gardens are useful on 

 account of their very rapid growth. They are not 

 particular as to soil, though they do best, like most 

 plants, when it is well manured.

 may be grown 8 to 10 ft. or even 12 ft. high.
