ONOPORDON (ancient Greek name). Comp6sita?. 

 The Scotch Thistle, O. Acanthium, is a vigorous bien- 

 nial plant, growing 5-7 ft. high, with cottony white, 

 spiny foliage, and heads of pale purple fls. l%-2 in. 

 across, borne singly on the branches. It is not adver- 

 tised for sale in America, but is sometimes cultivated 

 for "auld lang syne," and occasionally it is used with 

 striking effect by some lover of hardy plants. It is 

 then placed against a background of dark shrubbery, 

 which sets off the silvery foliage and bold habit of the 

 Scotch Thistle. The plant is rarely found growing wild 

 in the Atlantic States, having come from Europe. The 

 Scotch Thistle will probablv never be a weed of the 

 first importance in America', as is the Canada Thistle. 

 Nevertheless, care should be taken not to let it go to 

 seed. A white-fld. Scotch Thistle was advertised in 

 Germany in 1894 as a horticultural novelty.
