234 ARISTOCRATS OF THE GARDEN 



yellow in color. In 5. Wilsonianus the spike is 

 cylindrical, like an enormously elongated thyrse, 

 and branching at the base, and the flowers are deep 

 yellow. In both of these plants the actual length of 

 the spike clothed with flowers is from two to three feet. 

 Strong clumps of these three Senecios produce in 

 August and September a dozen or more flowering 

 spikes bearing many hundreds of flowers and are 

 extremely attractive. 



Quite different from the above but equally charming 

 is S. tanguticus which grows from four to five feet tall 

 and has finely cut foliage and pyramidate panicles from 

 eight inches to a foot high of clear yellow flowers. The 

 individual flowers are small and the whole plant sug- 

 gests a glorified Golden-rod (Solidago). These Sen- 

 ecios may be easily raised from the seeds which are 

 freely produced and the seedlings grow rapidly and 

 soon make strong flowering plants. Senecio tangu- 

 ticus is apt to make itself too much at home and must 

 be watched or it will usurp the whole waterside or 

 border. 



Closely allied to the above-mentioned plants but 

 totally different in appearance is Artemisia lactijlora. 

 This new Wormwood has finely divided, Chrysan- 

 themum-like, aromatic leaves and large feathery 

 panicles of milk-white, fragrant flowers borne on
