Cult. These are very pretty plants when in blossom, and are, 
therefore, well worth cultivating. A mixture of light turfy 
loam and peat is a good soil for them; and cuttings strike root 
readily in the same kind of mould under a hand glass, but as 
they are liable to rot, air should be frequently given.
