Water and stones alone do not make a healthy pond. It needs plants, which provide habitat for animals and filter nutrients out of the water, keeping it clearer and resistant to algal blooms. Plus, when you fill a pond with plants, you can call it a “water garden,” conjuring images of fragrant blossoms nodding at their reflections in limpid pools. Ideally, a pond will have both plants that live fully in the water—submerged plants rooted to the bottom as well as floating ones—and marginal (or “emergent”) plants that live on the banks in perpetually damp soil.
