prepared to receive them, into which the}' should ])e put al about 



six inches distance each wa}^ the tops of the roots being kept a hlllc 



below the surface of the ground, and the earth pressed close to the 



roots. If the following spring prove dry, they should be duly watered, 



to forward iheir growth. The plants may remain here two years, by 



which time they will be fit to transplant where they arc designed to 



grow, removing them in the autunm, as soon as their leaves decay, 



great care being taken in digging them up, not to cut or break their 



roots, as that greatl}' weakens them. They require afterwards no 



other culture, but to dig the ground about them early in the spring 



before they begin to shoot, and in the summer to keep them clean 



from weeds. The roots continue many years, but the stalks decay 



every autumn; the same roots not flowering two years together, or 



seldom oflener than every third. When they flower strong, they 



have, however, a line aj)pearance. 



The first is mostly propagated by ofl-sets or parting the roots, 

 and planting them where they are to lemain in the early autumn ; 

 but in order to have the plants flower well, they must not be often 

 transplanted or parted. 



They are also capable of being raised from seeds managed as the 

 first sorts. 



They all succeed the most perfectly in moist loamy soils, where 

 there is a degree of shade. 



All the sorts are useful as ornamental plants, for the various 

 clumps, borders, and (piartcrs of pleasure-grounds ; those of low 

 growth being planted towards the fronts, and the latter kinds more 

 backward.
