RARE PERENNIALS, ALPINE PLANTS 
17 
FERNS —We have divided the Ferns into 
two sections; those which require very 
little, if any shade, and those which are 
true shade lovers. 
Dwarf Rock Ferns —The species listed be¬ 
low require very little shade, unless 
otherwise noted, and will thrive with 
very little moisture after June once they 
have become established. But they do 
require a very well-drained, stony soil, 
with plenty of leaf mold or peat and silt, 
and if possible should be planted so that 
the roots will be protected from the hot 
summer sun by burying the roots under 
a partly submerged rock. We advise 
planting these in spring if possible, and 
not later than end of October in fall.
