How to Read the Maturity Figures 
T the right of most variety names in this List you will find figures representing the 
approximate number of days required to mature the plants—from the time of plant- 
ing the seed to the time the vegetables are ready to eat, or the flowers to bloom. 
Maturity dates are valuable in making comparisons as to earliness or lateness of varieties 
under a general family name such as cabbage, beans, peas, radish, etc. Naturally there is 
a variation in the time of maturity at different points over the country. Our figures are 
based upon the growing conditions around Minneapolis, and the periods named were 
determined largely at our trial grounds. Our readings were made from tests in the 
open sunshine, grown in black sandy loam soil, with some artificial sprinkling.
