Different Types of Plants for a Water Garden
Three types of plants for a water garden that are most common in ponds and water gardens. Overview of the different groups.
Free Floating Plants
Are the most common addition to ponds and water gardens. They are used to enhance the look of the surface of the pond. They should cover no more than 40%-50% of the surface of the water. The plants are free floating and do not need to be anchored in soil, they absorb everything they need to live off directly from the water.
The plants provide surface cover shade for a pond that provides a place for fish to escape the mid-day sun. Floaters are sometimes prolific multipliers, so they may need to be thinned out on occasion.
Marginal plants typically float above the water, but their roots are usually anchored in a heavy clay loam. Plants are planted in fabric pond pots or plastic, no hole containers.
Submerged plants are generally located almost totally underneath the water, and aren’t very visible from the surface. Underwater plants reduce algae by consuming the nutrients the algae needs to grow. Their main job is as oxygenators, supporting fish and other animals.
They can be potted in gravel, because they don’t use their roots to collect nutrients.
