Not useless are ye, flowers ; though made for pleasure, 

 Blooming o'er field and wave by day and night ; 

 From every source your sanction bids me treasure 

 Harmless delight." 



ACHILLEA. 



Milfoil. 



A. ptarmica. Sneezewort. This is a desirable border

 is dark shining green. It is very hardy, and easy to cultivate 

 in almost any common soil. 



A. aurea, or golden- flowered, has rich yellow flowers, but 

 not so hardy as the last. 



We have a native species, A. millefoliu?n, known by the 

 common name of Yarrow ; of this I found a variety with pink 

 flowers, which is now in my possession, and is desirable in a 

 collection. ___

 garden. There are many species, all handsome perennial bor-

 are of a tuberous character, every piece of which will grow. 

 This should be done soon after they have done flowering ; and

 shade and moisture. Most of them have blue flowers, but
