white, while if not protected they become brown in color and are 



not as salable. The crop 

 ripens somewhat irregu- 

 larly When danger 

 of hard frost is appar- 

 ent the immature heads 

 should be pulled with 

 roots and leaves and be 

 planted out in a coll 

 cellar or cold frame, 

 where many of them 

 will form good salable 

 heads. The insect ene- 

 mies are the same as 

 those of the cabbage. 



Varieties. — There are 

 many varieties, but per-

KALE, or BORECOLE. (Brassica oleracea var.) 

 Native of Europe and Asia. — Anntial or biennial. — The seed 

 is like that of the cabbage or kohl-rabi. LTnder this head is 

 grouped a number of 

 vegetables closely re- 

 lated to the cabbage 

 and Rohl-rabi that 

 are used for greens. 

 None of them are 

 sufficiently hardy in 

 the extreme north to 

 stand out over winter. 

 They are here cul- 

 tivated in the same 



manner as turnips. In sections where the winters are mild, some 

 of them are esteemed for planting in autumn for early spring use
