FIG. 134. Gathering Swiss chard. Only the largest leaves should be picked; 

 the others should be left to grow. 



In many parts of the planting zone E, and farther 

 south, plants of yellow rocket grown from seed live 

 over winter and will supply leaves until the next spring, 

 when they soon run to seed. It is said, however, that 

 the plants can often be kept in good condition for two 

 or more years if the flower stalks are picked off before 

 the flowers open. 



Swiss chard. Swiss chard is a variety of beet that 

 develops large leaves with somewhat fleshy stems. It 

 does not have a fleshy root like that of the garden beet. 

 The culture of Swiss chard is the same as for the garden 

 root beets. The most satisfactory variety is the 

 Luculhis.
