Propagation and Culture. 1, 2, 5, 9, 12, 13 to 16. Thefie 
hardy forts may be propagated in plenty, by parting the 
.roots; the beft time for which is in autumn when the 
ftalks begin to decay. Tire firft and fifth require a light 
loamy earth, and funny expofure. The twelfth will 
thrive in almoft every foil and fituation. 
10. The feeds of this muft be fown upon a gentle 
hot-bed in the fpring, and when the plants are fit to re¬ 
move, they (houid be fet each in a feparate fmall pot, 
and plunged into a frefh hot-bed to bring them forward. 
In June they fhould be inured by degrees to the open 
air, and afterwards fome of them may be fliaken out of 
the pots, and planted in a warm border; where, if the 
feafon be good, they will flower in the middle of July, 
and ripen their feeds in the beginning of September. 
17. This is propagated by feeds, which fhould be 
fown on a warm border in autumn, and the plants will 
come up the following fpring : for, if the feeds are fown
