its fine double white flowers in ample corymbs, on erect 

 stems two or three feet high, have the appearance of snow. 

 From June to August. Leaves pinnate, downy beneath ; 

 the terminal leaflets larger, three-lobed ; the lateral ones 

 undivided. This and most of the species succeed best in 

 a strong, most soil, enduring the severest winter without 

 protection. 



The Golden-striped leaved Meadow-sweet is a variety 

 of the single Meadow-sweet, with leaves elegantly vari- 

 egated with golden-yellow. The flowers, which are not of

S. filiptfndula. Dropwort, is an herbaceous perennial 

 of easiest culture. It is so called from the manner in

 are bright rose or red. The foliage is elegant ; leaves pin-

 finer and more showy. It does not grow so high, and is 

 in flower all the season, throwing up a succession of flow-

 must be divided with care in August, to have a strong

 from the tuber, but not commonly. 



S. lobata. Lobed-leaved Spiraea. Queen of the Prai-

 flower-stems are two feet high, terminated by corymbs of 

 deep-pink or red flowers. It is not so long in bloom as 

 the last species and varieties, but fine in its season ; in 

 July. Leaves pinnate, glabrous; the odd leaflet large,
