In the first, the seeds should be sown either in the autumn, soon 

 after they are fully ripened, or in the spring, in a moist shady spot, 

 or in pots to be placed in such situations. When the plants appear, 

 they should be kept free from weeds, and have occasional water when 

 the weather is dry, being shaded from the heat of the sun. When 

 the stems decay, the}' may be carefully removed and planted in moist 

 shady places, at the distance of twelve or eighteen inches, to remain 

 till the following autumn, when they should be finally planted in the 

 borders and other places where there are due shade and moisture. 



The roots may be removed, and the off-sets carefully taken off 

 from them about the latter end of August or the following month, 

 and immediately planted in such situations as the above, when they 

 will be fully established before the frosts set in. 



These plants are found to be hardy, but incapable of succeeding 

 in dry soils or sunny situations. They afford ornament in the beds, 

 borders, or other parts of pleasure-grounds.
