Cult. This is a vast genus of what are called succulent 

 plants, that is, fleshy-leaved plants. The shrubby kinds should 

 be grown in pots, in a very sandy or gravelly soil ; they should 

 be kept almost quite dry, while in a dormant state, but when 

 growing freely and in the flowering season, they require a consi- 

 derable supply of water. The poorer the soil is, the more dwarf 

 the plants will grow, and bear flowers more abundantly. The 

 shelves in a greenhouse are a good place to preserve them through 

 the winter, however, a good dry frame will answer the purpose 

 equally well, if not better, with a covering of mats in frosty 

 weather. Cuttings of all of them strike root readily, if planted 

 in pots of the same kind of earth recommended for the plants, 

 and kept dry till they begin to wither, when they may have a 

 little water given to them ; and under this treatment they will 

 root very soon. There are also several annual and biennial 

 kinds, most of them handsome and curious. The seeds of these 

 should be sown in pots early in spring, and raised in a frame, 

 hot-bed, or greenhouse ; and when the plants are of sufficient 

 size, plant them singly in small pots, and set them in the green- 

 house, until the warm weather commences, when they may be 

 set out of doors along with the shrubby kinds, where they will 

 flower and seed freely, if the summer proves fine. The same 

 soil and treatment recommended for the shrubby kinds will also 

 suit these well. The ice-plant, M. crystMinum, and also M. pin- 

 natifidum do well if planted out on rockwork or among stones, 

 where they will make a very curious appearance.
