The macrophylla or large-leaved magnolia grows so rapidly 

 while young, that in our Northern States it is comparatively 

 tender, and requires to be protected for eight or ten years, or 

 until it seems to have arrived at comparative maturity, after 

 which we have found it perfectly hardy. In our Southern 

 States, or all south of Washington, it is one of the most beautiful 

 of the many beautiful trees of that semi-tropical region. 



The magnolia cordata is another Southern variety, but per-

fectly hardy in most sections of the Northern States. It makes 

 a tree of medium size, and is not desirable except for large 

 grounds or collections. The auriculata is a variety very similar 

 to the acuminata in general appearance, not quite as vigorous, and 

 does not make as large a tree, and for parks or pleasure-grounds, 

 where beauty, not a botanical specimen, is the point sought for, 

 it is not equal in value to the acuminata. 



The glauca or swamp magnolia is almost a sub-evergreen, 

 often retaining its foliage until January, even in our Northern 

 States.
