AGERATUM CCELESTINUM. 
Class, Order 
SYNGENESIA  POLYGAMIA ZQUALIS. 
It is supposed that this plant is from 
Sonth America, but its native country is 
not precisely ascertained. With us it re- 
quires the greenhouse protection during the 
winter. Its delicate flowers come out in 
the autumn, and last for two months or 
more. 
The plant is of erect, but low growth. 
It may be propagated by cuttings with little 
difficulty, and the soil should be light loam. 
If the branches become bare it is necessary 
to cut them down, which may be done with 
good effect at any time during the spring or 
beginning of summer.
