FOREWORD: Here, there and everywhere even the 
difficult ones among Great Plains plants are being 
grown successfully, by simple good fortune when 
the natural soil of the garden provides aeration and 
drainage, or by the expedients of artificial screes, 
sand beds, etc. 
A workable scree for general purposes is made up 
of one part gravel or stone chips, one of sand, one 
of ordinary soil. To this humus may be added as 
needed. A leaner, better drained mixture is recom- ~ 
mended for Penstemons, an extreme type for Cacti. 
Sand and gravel facilitate deeper wetting by light 
rains and provide drainage and aeration during 
downpours. A further aid in keeping crowns and 
woolly leaves of certain exacting plants relatively 
dry is a surfacing of hard stone chips, or fine gravel. 
SERVICE: High quality plants only are sent out 
on your order. We do not substitute without per-
