each could be carpeted over with an undergrowth of a suitable colour 

 and habit, so as more conspicuously to bring out the different hues 

 and habits of the plants used. The low-growing snowy Antennaria 

 tomentosa, the close glaucous Sedums and variegated Saxifrages, 

 would bring out the dark-green colour and strikingly sturdy appear-

 engraved from a photograph, or it would display itself to great 

 advantage dotted over an undergrowth, the mossy Mesembryanthe- 

 mum cordifolium aureum, or even the common Cerastium tomentosum. 



The fine dark grassy-green carpeting of Sedum lividum brings out 

 both the character and glaucous hue of Echeveria glauco metallica, fig. 4, 

 p. 53. Many of the Sempervivums grow to a considerable height, having 

 strong stems surmounted with a large table-looking rosette of beauti- 

 fully-formed leaves, and can therefore be associated, the dark greens 

 with groundworks of the more dwarf and glaucous Echeverias and 

 Sempervivums ; and carpeting for the more dwarf varieties can be 

 formed of glaucous Sedums and silvery Saxifrages, 



Some of the ioniums are exceedingly interesting-looking plants, 

 and very effective for this order of gardening. ^Eonium ciliare, fig, 5,

is one of the most interesting-looking of the dwarf varieties, and looks 

 well on a carpeting of such as Saxifraga rosularis or Sedum hispanicum. 

 These figures will, we hope, suffice to show the interesting character of 

 these plants to those who are not acquainted with them. 



All the dwarf hardy Sempervivums, Sedums, and Saxifrages multiply 

 themselves rapidly by offsets, and by being divided frequently a large
