HABITAT AND GARDEN SUCCESS 
To grow the Great Plains plants it is important 
to recognize native factors of adaptation and en- 
vironment. Character and faculty have been mold- 
ed in these plants by untold ages of living where 
periods of moisture shortage are long and of 
moisture excess very brief. 
Moisture retention devices in the plant structure 
have been developed to an outstanding degree to 
withstand shortage; to escape excesses the canny 
plants select high places and slopes, rocky, grav- 
elly and porous soils from which excess water 
readily drains away or down, thus quickly restor- 
ing aeration. In general, moistness is sought, wet- 
ness avoided. 
A recommended scree for replacing soils that 
are close textured and impervious, or too rich and 
moisture retentive, or to counteract inescapable 
shade from remote trees or other objects, is mixed 
from equal parts of ordinary soil, coarse sand, and 
fine gravel or rock chips, including some lime. 
This provides an excellent base for all Great Plains 
plants. The needs of certain subjects for portions 
of richer soil may be met by adding leaf-mold or 
other humus, locally, in planting or in top-dressing.
