plants select high places and slopes, rocky, gravel- 
ly and porous soils from which excess water readily 
drains away or down, thus aeration is renewed. In 
general, moistness is sought, wetness avoided. 
Rainfall on the Plains is often too infrequent 
for best growth, and so correct garden environment 
brings willing response and surprising performance 
and beauty. 
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 leafmold or 
other humus, locally, in planting or in top-dressing
