ae We the delightful flower and foliage effect of 
many tiny alpines in an easily constructed 
wall garden. Here of course, your selection 
of plants will be somewhat limited, but 
nevertheless there is still a long list of plants 
that are perfectly adaptable to this type of 

culture and some that will not thrive any- 
where else. With careful selection and planned planting you can have flowers 
all Summer long and ornamental foliage plants all through the year with the 
evergreen species. Inside the back cover of this book there is a partial list 
of plants that will thrive in dry walls. If you want to build a beautiful living 
wall, build it according to the accompanying sketch, slanting each stone to- 
ward the center. Instead of using cement to hold it together, use a compost of | 
two-thirds sandy loam and one-third leafmold, with a handful of dry sheep 
or cow manure or bone meal to each pail of compost. Be sure the greatest 
portion of the wall contains neutral to alkaline soil, necessary for most rock 
plants. Use the compost dry and fill in between stones as you would with 
concrete. 
The dimensions given for width are minimum sizes and the wall may 
-be made thicker if so desired. The thicker the better, but too thick and it 
will be a mesa and not a wall. A slant of two inches to a foot of height is 
enough to catch rain. Use rough, flat stones if possible—sandstone is the 
best medium, as it retains moisture longer.
