Although, like the rest of this section, (the Cape 
one excepted,) it is sufficiently hardy to resist 
the cold of our rigorous winters, upon a wa

plants; it succeeds better in a glass case, or 
greenhouse; and is even capable of thriving 
1n the heat of a stove. In the open air succu- 
lent plants of the more hardy kind, suffer 
more in our climate from wet than from cold.
