ARTHROTAXIS: Athrolaxis. 



ARTICHOKE (Cynara Scdlymus, Linn.). Com- 

 pdsilie. The artichoke (or the Globe artichoke, to 

 distinguish it from the Jerusalem artichoke) is a strong 

 thistle-like plant (Fig. 389), grown for the edible flower- 

 heads fFig. 390). It is native in southern Europe and 

 northern Africa, and is not hard>' in the northernmost 

 parts of the United States. It is perennial, but the 

 plantation should be renewed every two or three years. 

 See Cynara. 



The artichoke is propagated by seed or by suckers. 

 The latter is the preferable method, for a good strain or 

 variety may thus be perpetuated. The buds or shoots 

 are detached from the old crown in spring before 

 growth begins. Seeds produce bearing plants the fol- 

 lowing year, although heads may be secured the same 

 autumn if the season is long and if the seeds are 

 started early under glass.

 the thickened base of the scales (or involucre bracts)
