Pond plants can provide several benefits to your garden's water feature. In addition to their beauty, pond plants reduce algae growth by consuming a portion of the nutrients that algae need to generate. Also, pond plants give shelter to fish and other pond occupants. Duck potato, cattails, and wetland grasses are plants to consider for your pond.
Duck Potato gets its name from the tubers formed by the plant's roots, which waterfowl, songbirds, and beavers enjoy eating. The perennial grows up to four feet tall, and its green leaves can become up to 12 inches long. White blossoms with three petals appear from early spring to late summer. While the plant prefers full sun, it can grow in other conditions. Duck potato can be planted from seed in the spring or fall. However, bulbs (tubers) should be planted in spring. This plant is recommended for USDA landscape zones 5-10.
Cattails, also known as bulrush, have flat, green stalks. They are named for their brown seed heads, which appear throughout summer. Since cattails can get close to 10 feet tall, they provide visual interest to your aquatic garden. This plant is a hardy perennial that grows well in full sun and part shade. They can be built from the bare rootstock, seedlings, or seeds. They have rhizomatous roots but can be added to your garden as a container plant if desired. This plant is recommended for USDA zones 3-10.
Wetland grasses make unusual pond plants because they love soggy soil. These perennials are easy to grow and add beauty and texture to your pond. Since wetland grasses are available in many varieties, you can choose the ones with the colors, shapes, sizes, and landscape zone to suit your garden. The right combination of grass varieties can make your pond's appearance genuinely stunning.
