PLANTS FOR MOIST SOILS 
MOST plants will not stand a location that is quite moist a great deal of the time. 
These varieties, however, do not seem to mind considerable moisture if proper drainage 
is provided. In many cases it increases their growth and gives them finer foliage. 
Care must be used in choosing varieties that will best suit your particular location 
and we are prepared to help you plan correctly.
