VII. HARDY NATIVE FERNS AND PLANTS OF SIMILAR 
CULTURE 
The native ferns are not as easily cultivated in this part of 
the country as in the more moist eastern sections. They are, 
however, well worthy of attention if proper location for their 
culture can be had. Most of the ferns require shade, leaf 
mold, and moisture, such as is afforded in their natural 
environment. Thcse who are fortunate enough to have a nat- 
ural ravine through which a small stream flows and which is 
shaded by a growth of deep-rooted native hardwood trees are 
in possession of a proper location for a fern garden. If the 
soil is not naturally rich in leaf mold this deficiency should 
be remedied before planting the ferns. 
The location suitable fcr most of the ferns will also be ideal 
for the growing of some of our rare and beautiful perennials. 
A few of the latter have been appended to the list, as well as 
some particularly interesting and desirable shrubs and small 
trees suitable for an undergrowth to the larger trees and as 
a background for the ferns and perennials.
