Rock Plants 
Rock plants thrive under adverse conditions and are at¬ 
tractively used as a border edging for the pool itself or for 
a perennial bed around it. The pool may be edged with 
rough stone and any crevices that will hold a handful of soil 
will accommodate one or more interesting rock plants.
