Cult. All the species of this genus are very ornamental. 
The hardy kinds thrive best in peat earth, or a very light sandy 
loam : they are dwarf shrubs, and are therefore well fitted for 
the front of shrubberies, where the soil will suit. By layers 1$ 
the usual mode of increasing them, but they also strike root rea- 
dily from cuttings in sand under a hand-glass. The greenhouse 
kinds are well adapted for large conservatories, and they thrive 
in the same kind of soil recommended for the hardy species. 
Cuttings taken from wood not too ripe will strike root readily 
in sand under a hand-glass. All may be raised from seeds, 
which in most of the species ripen in plenty.
