season, which readily take root. They thrive most perfectly on old 

 walls, buildings, or rock- works. Where cuttings or roots of the 

 perennial kinds are planted in some soft mud, placed upon such 

 situations, they quickly take root and spread into the different joints 

 and crevices, covering the whole in a very short time. 



The seeds of the annual sorts also, when sown soon after they 

 become ripe in such situations, soon come up and support them- 

 selves without further trouble. 



Most of the perennial sorts are kept in the nurseries in full 

 plants, fit for setting out in the borders, pots, &c. either in the spring 

 for flowering the same year, or in the autumn to flower in the follow- 

 ing year. 1 



These plants may be planted out in any dryish light soil, in 

 borders, beds, and other places, and in the sides of dry banks, or in 

 any elevated rubbishy soil, as well as in pots to move to different 

 parts occasionally ; or also some of the evergreen kinds, to introduce 

 in their pots among winter plants under shelter, to increase the 

 variety. Jn most sorts, they may also be introduced as rock plants, 

 to embellish artificial rock-works, ruins, and other similar places in 

 pleasure-grounds. The Stonecrops and other low trailing kinds may 

 also be made to occupy the tops of any low walls, pent-houses, 

 sheds, or other low buildings. 



The twelfth and thirteenth sorts may likewise be disposed in 

 patches towards the front of borders, &c. as they spread thick and 

 tufty close to the ground, and flower abundantly; and being planted 

 in pots, are proper to place in the outside of windows, copings of low 

 walls, and in balconies, and court yards, in assemblage with other 

 low fancy plants; they will closely overspread the surface, and 

 flower profusely as far as they extend.
