HARDY FERNS 
Hardy ferns are some of the most useful plants for landscaping and 
foundation plantings. They are especially well adapted for foundation 
plantings along the shady side of building where few other plants succeed. 
They form a suitable combination with wild flowers and shrubs, and add 
charm to the shady garden nook. 
In their native habitat they grow in leafmold, rich alluvial soils and 
peat bogs. They will, however, thrive well in garden soil to which have 
been added humus in the form of peat, muck, leaves from deciduous trees. 
or lawn clippings. A winter mulch of such material will be beneficial and 
should not be removed in spring. 
Ferns should be planted while dormant. They may be planted in fall 
after frost has killed the fronds and again in spring before new growth 
takes place. We can ship at any time from Sept. 15th to May 15th. 
Freezing will not damage the dormant roots and if they arrive in 
frozen condition, we suggest they be spread out in a cool place and sprinkled 
with water to allow thawing out slowly. Before planting they should be 
soaked in water for a day or so and well watered after planting. 
Following is an index showing their adaptability to various conditions: 
R—adapted for Rock Gardens; S—for shade; B—for the border; M—Moist 
conditions; O—Open sun. Those best adapted for foundation planting are 
so indicated. 
American Maidenhair. (Adiantum pedatum)—RS Foundation.
