Peach Varieties, Botany and Classification 353 



made or in one in which the conditions are similar to those 

 where the new orchard is to be established. 



The peach varieties named in the lists below show the 

 principal sorts that are now being grown in different sections 

 of the United States. The approximate date when each one 

 ripens in the sections where grown is also shown. These 

 variety lists and the appended dates are based largely on the 

 experience of commercial peach-growers in the different 

 sections indicated. The ripening dates, however, though 

 supplied by growers, should be considered in the light of 

 several facts : There may be variations in the date of ripen- 

 ing of a variety in the same orchard in different years of one 

 to two weeks or even more, due to climatic or other con- 

 ditions. Very vigorous trees, as when stimulated with 

 nitrogenous manures, will ripen their fruit later than less 

 vigorous trees of the same variety. The sequence of ripen- 

 ing of varieties, especially w^hen they normally mature rather 

 close together, may not be the same in successive years, even 

 in the same orchard. Moreover, the sequence may vary 

 somewhat in different regions. Differences in elevation make 

 wide differences in the ripening of a variety even in orchards 

 in the same locality ; the higher the elevation, the later the 

 date of maturity. The ripening dates, therefore, while of 

 much help in selecting varieties for planting, should be con- 

 sidered as relative and approximate only with regard to any 

 one season, rather than as absolute and definitely fixed 

 occurrences. 



With these precautions, the following lists should prove 

 helpful to the prospective planter. The arrangement of the 

 lists is alphabetically by states. The region to which each 

 list applies is indicated by the name of an important peach 

 center or district, together with the general section of the
