ARTICHOKE 303 



GLOBE ARTICHOKE (Cynara scolymus) 



Description and Culture. Native of Barbary and 

 South Europe. A perennial. This is a large thistle-like 

 plant growing two to three feet high, producing large 

 flower heads, the scales of which are large and thick and 

 are highly esteemed as a garden vegetable in England 

 and southern Europe. It has, however, never become 

 popular in this country, and is rarely grown. In southern 

 Europe it is grown by divisions, and there are many varieties. 

 It may also be grown from seed, but seedlings are generally 

 very much inferior to other sorts. The roots must be 

 very carefully protected in order to bring them through 

 Northern winters.
