The eighth sort, as it rarely produces seed in this climate, may 

 be best propagated from its trailing branches, which, if planted in 

 April, will take root and become good plants by the following au- 

 tumn, when two or three of them may be placed in a common frame 

 for shelter in winter, in order to preserve the species; as in hard 

 winters, those which are exposed are sometimes destroyed. 



This is properly a rock plant, being hardy, and forming with 

 very little care a neat tuft of flowers, and is not apt to encroach on 

 its neighbours. It is valuable as an ornamental plant from its be- 

 ginning to flower in March, and continuing through the summer. 

 All these plants may be employed in borders for the purpose of 

 affording variety, and some of them in the way of adorning rock 

 works.
