3. Choosing varieties. — Great progress has been made in the 

 development of varieties. There are now so many good varieties 

 that it is often difficult to decide which are best for a particular 

 purpose. 



Varieties diflFer in vigor and habit of growth (Tra: 97-111). 

 For example, the plants of the Stone, an old well-known 

 sort, are vigorous and 

 spreading, those of 

 the Earliana are not 

 so vigorous, and . the 

 plants of a variety 

 like Dwarf Stone are 

 vigorous and upright 

 in habit of growth. 



Some varieties, as 

 the Earliana, mature 

 early, while others, as 

 the Stone, mature late. Again, varieties differ in the color of the 

 fruit. Red kinds predominate ; there are many pink and purple- 

 fruited varieties and a few yellow ones. 



Among the early varieties, Earliana is the best known and the 

 most largely grown. The plants are productive, fruits are red in
