A very common plant in gardens, rising from 1 to 2 

 feet high, and flowering in August and September. It is a 

 native of North America, where it grows in shady woods 

 from Canada to Virginia. When wild its stem does not 

 usually bear more than from 6 to 10 flower-heads; but in 

 the cultivated plant they are often exceedingly numerous, 

 as is shewn in our figure. The leaves are deeply and 

 rather widely serrated, but at some distance from the 

 apex are perfectly entire. 



By favour of M. Achille Richard we possess a specimen 



From 



lip/ife, wide-spreading ; in allusion to the creeping offsets.
