There are 3 basic types of plants that are commonly used in the pond. They include:
• Floating Plants – This type of plant include Hyacinth, Lilies, etc. They are useful in the respect that they add beauty, block out sunlight keeping water temperature cool and help prevent algae growth. Floating plants come in all sizes from very small (duckweed) to over a foot in diameter (water hyacinth). Most have roots that hang in the water from the floating green portions.
• Emergent Plants – Also known as emersed, this type of plant includes Cattails, Grasses, etc. These plants are rooted plants often along the shoreline that stand above the surface of the water. The stems of emergent plants are somewhat stiff or firm. They add a tall background to the pond landscape.
• Submerged Plants – This type of plant includes Anachris, Hornwort, etc. These plants are rooted plants with most of their vegetative mass below the water surface. One discerning characteristic of submerged plants is their soft stems, which is why they do not usually rise above the water’s surface.They contribute oxygen and biological filtration to the pond as well.
