Goldfish ponds are a beautiful addition to any garden, and goldfish are hardy fish that can survive outside in ponds during the winter months, even in very cold climates. But, they will need goldfish pond plants, which will make them feel more comfortable as well as giving them a place to hide from outdoor predators.
There are many different types of goldfish pond plants, some are more decorative, and some are necessary to maintain oxygenation of the water and to clean waste material that may be in the pond.
But plants are not just for utilitarian purposes in garden ponds, they are also attractive and fragrant, and there are plants available to please just about any aesthetic taste.
Water Canna plants are a popular choice for outdoor ponds, as they grow attractive flowers in a wide variety of colors. They require about six hours of sun a day to keep them blooming, and after blooming the dead flower stalks should be removed to make room for new blooms. This is one of the taller goldfish pond plants, and they can reach as much as 6 feet in height.
For highly effective oxygenation of the water, Anacharis is one of the best choices. However, I must warn that in some states, this plant is illegal to sell as some species of the plant, like Brazilian elodea and hydrilla, can become highly invasive to local ecologies if released in the wild. They spread quickly and crowd out native plants, as well as impede boating, swimming and fishing. Eradication is difficult and many times impossible. Use this plant in your pond at the risk of your local waterways.
The Anacharis plant does provide excellent hiding places for goldfish, as well as an area where they can lay eggs. This is one of the best goldfish pond plants, as it will also clean the water, absorbing fish waste and other dissolved materials that may be in the water. Anacharis is not as hardy in the coldest temperatures, preferring climates up to zone 5, and temperatures of at least 62 degrees.
Lotus plants are a classic pond plant since ancient times, and do wonderfully as goldfish pond plants. White is the classic color of lotus blossoms, but they also come in yellow, pink, and some bi-color varieties. They do well in heat, and will bloom in the late summer.
The lotus is well-loved because of the fragrance of the blossoms, which carries in the wind. Depending on the variety of lotus that you purchase, it may be hardy anywhere from a zone 10 to a zone 5. It is important for that reason to make sure of what variety it is before purchasing. The lotus needs sun for about six hours a day or more. The height of the plant can reach as high as 60 inches.
Hibiscus Varieties and Care
Hibiscus comes in many different varieties of goldfish pond plants, and all are easy to care for. The Moschuetos variety comes in large flowers in red, white and pink, and blooms in later summer. The coccineus variety grows to as large as 8′ tall, and has bright scarlet blooms. The foliage itself will turn bright red in fall.
Hibiscus plants should be fertilized every two weeks. A pond fertilizer tablet is a good idea for most goldfish pond plants, and for hibiscus it is highly necessary. Hibiscus also need some direct sunlight, but beyond that do not need a great deal of care.
Different hibiscus varieties have different zone requirements, but some are hardy up zone 4. Most varieties will grow the best in zones 5 through 8. Most hibiscus will bloom from the summer through to the first frost.
