Marginal Plants
These attractive, hardy plants come in myriad sizes, shapes, and colors. These plants benefit the pond by removing excess nutrients that could otherwise feed algae. Marginals grow best in shallow waters or a bog at the edge of the pond. A bog area is shallow, about 6” deep, lined with pea gravel and filled with plants. Water is pumped up to it, then it flows through and over a waterfall or entrance into a pond.
