(A) Joe Pye Weed (Eupatorium purpureum) Is a 
very familiar and pretty species. The simple, rather 
slender, stem is very tall, attaining heights of from 2 
to 10 feet. The stem is usually stained purplish and is 
set at intervals with whorls of three to six, rough, 
coarsely-toothed leaves; these latter have short stems, 
rather broad bases and are sharp-pointed. The flowers 
grow in flat-topped terminal clusters. Each floret is of 
a rosy purple color and has projecting styles that give 
the flowers a very fuzzy appearance. 
Joe Pye Weed is commonly found in moist places 
from Newfoundland to Minn, and southwards, flowering 
during August and September. 
(B) Thorough wort ; Bone set (Eupatorium perfoli- 
atum) is a flowering herb, dearly beloved by the old- 
fashioned housewife and equally detested by the small 
boy. It was, and still is, one of the most commonly 
used home remedies. The stem is stout, hairy and 1 to 
5 feet tall. The opposite leaves are perfoliate, that is 
the ends are joined together. It is very common in 
swamps or thickets everywhere.
