MARYLAND—AQUATIC PLANTS AND GOLDFISH 
HARDY FLOWERS 
for Margins and Barhgrounds 
Your pool dressed up in a new gown of hardy plants along its edge or a stream of water with flowering plants along 
its bank will look much better than with weeds or grass growing there. 
You have, no doubt, asked yourself the question as to just what you could place around your pool or along the edge 
of a stream. You want those plants which will harmonize with the aquatic plants in your pool. This is not an expensive 
proposition. Those plants which require plenty of moisture are the ones best adapted, and we list below plants which we 
think are especially adapted to the surroundings of your aquatic plants. We believe that you will find the perennials which
