FOREWORD: ‘To grow the Great Plains plants it 
is important to recognize native factors of adapta- 
tion and environment. Character and faculty have 
been molded in them by untold ages of existence 
where periods of moisture shortage are long and of 
moisture excess mostly brief. Yet strange as it may 
seem, many have made no apparent effort at emi- 
gration. 
To withstand shortage moisture retention de- 
vices in the plant structure have been developed to 
an outstanding degree; toa escape excesses the wise 
plants select the high places and slopes and rocky, 
gravelly and porous soils from which excess water 
readily drains away or down, renewing aeration. In 
general moistness is sought, wetness is avoided. 
Truthfully, rainfall on the Plains is often too in- 
frequent for best growth, so that garden environ- 
ment brings willing response and surprising per- 
formance and beauty. 
A recommended “scree” for replacing soils that 
are too rich and moisture retentive or close tex- 
tured and impervious is mixed from equal parts of 
ordinary soil, coarse sand, and fine gravel or rock 
chips, including some lime. This provides an excel- 
lent base for all Great Plains plants. The needs of 
certain subjects for portions of richer soil, leafmold, 
or other humus may be met by adding these ele- 
ments, locally, in planting or in top-dressing.
