Water Lily (deep-water plant)

This flowering pond plant is one of most recognizable due to its lotus-like blooms and round lily pads that float on the surface. You’ll often find small fish using a lily pad as a shelter from the sun. Lily pads also provide a resting spot for frogs and dragonflies. Water lilies originate from temperate and tropical climates.

How do water lilies grow?

The pads are attached by a long stem to the pot of soil, set at the bottom of the pond. The flowers float on the water’s surface, suspended on thin stalks. Water lilies may be planted in containers and then sunk into the pond, or plant rhizomes may be buried in the soil at the bottom. Water lilies prefer to grow in water that is a depth of 18 to 24 inches.

Rodgers Flower (Bog Plant)

Rodgers flower rewards pond visitors with views of attractive flower spikes and abundant foliage. This pond perennial is taller than other aquatic plants (3 to 4 feet), so it’s a good idea to place it as a backdrop to shorter plantings. Light pink flowers appear on large plumes in late spring. The leaves are large and feel coarse to the touch. In spring, bronze-colored leaves appear. They gradually turn to green in summer, followed by reddish-bronze in fall. Plant rodgers flower at the edge of a landscape pond or water feature.

Horsetail Rush (Bog Plant)

This plant doesn’t produce flowers, but the cylindrical green stems show off attractive black-green bands. Dragonflies are often seen perched on a branch. Horsetail rush is often grown in Japanese-style gardens and is best planted at the water’s edge. Horsetail rush will quickly spread, so it’s best to plant it in pots.

What plant types grow best at the edge of a pond?

Zebra Grass is a striking perennial grass that displays yellow-striped foliage on slender, arched leaves. In autumn, the leaves turn a deep gold color, and then gradually turn to a soft tan in winter. This distinctive ornamental also displays pinkish-copper plumes in late summer, which turn to silver in fall. Zebra grass grows in a compact, gently arching clump and grows to 7 ft. in height and 4-6 ft in width. This attractive plant stands out next to a backyard pond and provides plenty of winter interest.

Are some pond plants invasive?

While many native aquatic plants work well in or at the edge of a pond, some non-native tropical varieties can be invasive, particularly in mild climates. Tropical pond plants are sold at garden centers for planting in or near ponds, or water features. When controlled these plants are fine. However, if they are allowed to migrate into natural ponds, lakes, or streams, they can overtake native species and affect the balance of the water ecosystem. Enjoy your tropical pond plants, but make sure to keep their growth by planting in pots, hand trimming, or another containment method. Or choose only non-invasive plants such as:

  • Yellow pondlily
  • Water poppy
  • Fanwort
  • Canadian pondweed
  • Water lilies
  • Cape pondweed
  • Water fern
  • Water clover

  • Keep the water temperature cooler
  • Provide a shaded area for fish
  • Submerged plants are important to spring breeding. Female Koi attach fertilized eggs to the leaves or stems.
  • Prevent the spread of algae which keeps the water cleaner
