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 
much account, are of a greenish-white.

of easiest culture, It is so called from the manner in 
which its tuberous roots hang together by threads. The 
flowers are arranged in corymbs, somewhat flattened. It 
is very handsome in bud, just before blooming; the buds 
are bright rose orred. The foliage is elegant; leaves pin-

pendula plena, is one of the finest hardy perennials. It 
possesses all the elegance of the single variety in its foli- 
age; while the mass of its pure white flowers is much 
finer and more showy. It does not grow so high, and is 
in flower all the season, throwing up a succession of flow- 
er-stems until frost. The tuberous roots of this species 
must be divided with care in August, to have a strong 
bloom the following season; care must be taken to pre- 
serve an eye on each tuber, as in dividing the Peony, or 
the root may fail, Sometimes sprouts will be thrown out 
from the tuber, but not commonly. 
8. lobata.—Lobed-leaved Spira. —Queen of the Fak
