BOG PLANTS 
AND NATIVE ORCHIDS 
CALTHA PALUSTRIS 
To the group of plants which can be conveniently classed as Bog Plants belong 
some of the most interesting varieties of our American flora. These require a damp 
situation in which the moisture must be constant yet not excessive. 
Native Orchids can be successfully grown under the right conditions. The 
Cypripedium acaule should be planted where the soil is very light, composed 
chiefly of sand and where the drainage is exceptionally good, and should always 
be planted in the shade. The Cypripedium spectabile requires boggy conditions 
where there is constant moisture. The Cypripedium pubescens will grow either 
under boggy conditions or in a rich wood soil in the shade.
