ARONICUM ARTEMISIA 



65 



Flowers, in early summer, and con- 

 tinuing a long time ; lilac, white, or 

 deep rose, in a roundish head, on 

 stems 3 to 6 in. or more high. Found 

 on the shores of the British Isles, and 

 on the tops of the Scotch mountains 



and the Alps of Europe. The deep 



rose is the best variety, and it is 

 useful as an edging in the spring 

 garden, for bare banks or margins of 

 shrubberies, and for rockwork, in ordi- 

 nary soil. Increased by division, which 

 is desirable every two or three years, 

 as old plants do not bloom so freely as 

 young ones.
