Annual. China, India — a garden crop. A correspondent of 

 w The Garden " (Nov. 18, 1893) who had grown this cabbage in 

 England, regarded it as worthless boiled as a vegetable, but of 

 great value and excellent as a late autumn salad — " white, crisp, 

 and sharp as the best summer cos lettuce." In China the 

 Shantung cabbage is grown everywhere but attains its greatest 

 perfection in the colder parts ; it is the favourite variety amongst 

 the half dozen other varieties cultivated, eaten fresh or preserved 

 by salting and drying in the sun ; the Chinese prefer their owi 

 varieties to the common European cabbage also widely culti- 

 vated there; but the same author considers that "from \ 

 European standpoint no variety of Chinese Cabbage is worth 

 growing being so very inferior in tlavour to our own." — (Wilson, 

 " A Naturalist in W. China," ii. (1913) p. 56). . 



The Shantung Cabbage was grown at Kew in 1888 from seed 

 sent by the Commissioner of Customs at Chefoo and seeds ripened 

 at Kew were distributed to correspondents interested in new 

 vegetables. Enquiries recently made show that interest in the 

 plant seems to be reviving.
