Crops Grown for Their Leaves 239 
Fic. 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 varitty 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 
Lucullus.
