178 Mr. Haworth on the Genus Sedum. 



Obs. It maybe worth mentioning that all the above de- 

 scribed plants, (save No. 1 ) are grown in proportionably 

 large pots of common light unmanured garden earth; 

 that they stand out of doors in the full sun, watered as 

 freely as green-house plants during spring and sum- 

 mer, and that they are regularly shifted and pruned in 

 September ; and in winter every pot is laid down side- 

 ways, to keep out superfluous wet, and the head of 

 each pointed to the south. In winter they are only 

 watered occasionally. With such treatment hardy 

 succulent plants succeed, and flower very well, and 

 assume the short and natural habit of their species 

 upon walls and native rocks. But when planted in the 

 borders or garden rock-work, they often smother each 

 other, or grow luxuriantly rude.
