The most healthy plants of this species are those which 
are either raised from seed in this country, or imported when 
small and in a growing state. Whenever the seed is ripe it 
should be sown in sand and placed on a warm dry shelf; it 
will vegetate freely, and the seedlings should have very little 
water. ‘They will root well in the sand, and need not be 
potted until they are pretty strong plants. The best soil for 
potting is loam, peat, and brick rubbish, but it should never 
be very rich, and the pots must be well drained. 
The practice of growing plants of this kind in dung or tan 
frames has been very much eulogised, and some specimens 
which have been sent from the continent to this country, 
reared in this manner, were certainly healthy and beautiful. 
Those who adopt this system in summer, must however 
take care to remove their plants into a dry atmosphere before 
the approach of winter, or they will be very apt to lose some 
of their finest specimens. 
The present species will live in any cool dry atmosphere 
a few degrees above the freezing point in winter, but will not 
grow or flower under a temperature of 55» or 60°.
