The Sempervivums are of great value for bedding, and some of 
the most useful are perfectly hardy. Perhaps the best ior edging s 
S. Californicum, which may be used in a similar manner to the 
SEMPERVITCM CALIFORXICUM. 
BEMPEIIVIVUM TABIJL.EFORME. 
dwarf-growing Echeverias ; it is readily propagated by offsets, which 
are produced in plenty, but not so freely as to render them objec- 
tionable. The common houseleek, S. tectorum, maybe employed for 
the same purpose as the preceding, but it is not so rich in colour, 
and the offsets are produced in such a plentiful manner as to quite 
spoil their symmetrical appearance. S. globiferum, S. hirtum, S. 
montanum, S. umbillicum chrysanthemum are all hardy, and are also 
useful for edging purposes. 
There are several half-hardy kinds which have proved here to he 
of great value for bedding. The'table plant, S. tabulseforme, is one 
of the most valuable of these, especially for edging purposes ; it has 
not been employed very extensively as yet, because it lias been scarce ; 
there is, however, no great difBculty in its propagation, for within a 
very short period I have succeeded in raising several thousand. S. 
arboreum atropurpureum, S. a. variegatum, S. Donckelaari, S. holo- 
chrysum, S. Toungi, and several others, are also useful for planting 
in the centres of carpet and other beds, as they form very pretty 
specimens. 
In forming edgings of Echeverias or Sempervivums of dwarf 
growth, it is most important for the edge of the bed to be firm and 
perfectly straight ; the sides of the bed should slope slightly, and if 
two or more rows of plants are planted, a little cement should be 
mixed with the soil to keep it in its place. It is a very good plan to 
mix equal parts fine soil and cement together, and with the mixture 
form a face to the slope ; the plants must, of course, be put in 
position before the cement has had time to set.
