Summary
Myriophyllum aquaticum, also known as parrot feather or parrot feather watermilfoil, is a freshwater aquatic plant in the family Haloragaceae. It is native to South America, but has been introduced and has become invasive in many parts of the world, including North America, Europe, and Asia.
The plant is an emergent perennial and can form dense stands in shallow water, such as ditches, ponds, and lakes. It has feathery, bright green leaves arranged in whorls of 4-6 around the stem. The leaves are finely divided and resemble the feathers of a parrot. The plant produces small, inconspicuous flowers that are pollinated by insects, and it reproduces primarily through fragmentation of its submerged stem.
Parrot feather watermilfoil can be a major problem in freshwater systems. Its dense stands can outcompete native aquatic plants and disrupt the natural ecological balance. The plant also can reduce water quality and make recreation activities like swimming and boating difficult. This invasive aquatic weed can also clogs up water inlets and outlets to hydroelectric dams, leading to loss of power.
There are several methods for controlling Myriophyllum aquaticum, but each method has its own advantages and disadvantages. Physical control method such as manual removal, or using a rake or hoe to remove it from the water surface, is effective but very labor-intensive. Chemical control methods, such as applying herbicides, can be effective but can also be harmful to non-target plants and animals. In some cases, biological control methods, such as introducing insects or other organisms that feed on parrot feather, can be used. Cultural and environmental management such as limiting nutrient input to the water body and increasing water flow can also help to prevent the establishment of parrot feather.

Parrot's Feather, also known by its scientific name Myriophyllum aquaticum, is an aquatic plant species that is native to the Amazon basin of South America. It is a popular aquarium plant and is also commonly used in outdoor ponds and water gardens. Parrot's Feather is highly adaptable and easy to grow, making it a popular choice among aquatic plant enthusiasts.
Physical Characteristics
Parrot's Feather has unique feathery leaves that are arranged in a whorled pattern around the stem. The leaves are bright green and can grow up to 4 inches long. The stems of the plant can grow up to 4 feet in length and float on the water's surface or grow submerged in the water. The plant produces small, inconspicuous flowers that are not often seen in cultivation.
Growing Requirements
Parrot's Feather is a highly adaptable plant that can grow in a wide range of conditions. It prefers warm water temperatures between 70 and 80 degrees Fahrenheit and a pH range of 6.5 to 7.5. It can be grown submerged in the water or floating on the surface, and can tolerate a wide range of lighting conditions from low to high. It also prefers nutrient-rich water and can benefit from regular fertilization.
Propagation
Parrot's Feather is a fast-growing plant that can quickly take over a tank or pond. It can be propagated through stem cuttings or by removing and planting the side shoots that form along the stem. The plant can also produce seeds, but this is less common in cultivation.
Uses
In aquariums, Parrot's Feather is often used as a background plant to create a natural-looking aquatic environment. It can also be used to provide shade and shelter for fish and other aquatic animals. In outdoor ponds and water gardens, the plant is often used to provide natural filtration and oxygenation for the water. It can also help to prevent the growth of algae by absorbing excess nutrients from the water.
Invasive Species
Parrot's Feather has become an invasive species in many parts of the world, including the United States, where it is considered a noxious weed in several states. The plant can grow rapidly and outcompete native vegetation, leading to a decline in biodiversity. It can also clog waterways and impede the flow of water. As such, it is important to properly dispose of any Parrot's Feather plant material and to avoid introducing it to natural waterways.
In conclusion, Parrot's Feather is a popular and highly adaptable aquatic plant that can be used to enhance the aesthetic and ecological value of aquariums, ponds, and water gardens. However, it is important to be mindful of the potential for the plant to become invasive and to take appropriate measures to prevent its spread. By following responsible cultivation practices, we can enjoy the beauty and benefits of Parrot's Feather while minimizing its negative impact on the environment.
More Information about Parrot's Feather
Parrot's Feather has been used for centuries in traditional medicine to treat a variety of ailments. In South America, it has been used to treat skin conditions, coughs, and other respiratory illnesses. Some studies have suggested that the plant may have anti-inflammatory and antimicrobial properties, although more research is needed to fully understand its medicinal potential.
Parrot's Feather is also a valuable source of food and habitat for aquatic wildlife. The plant provides shelter and nesting sites for fish, amphibians, and invertebrates. It also serves as a food source for some species of herbivorous fish, such as the grass carp.
Despite its potential benefits, Parrot's Feather can also pose challenges for aquatic plant management. When introduced to natural waterways, it can rapidly colonize and outcompete native vegetation, leading to significant ecological damage. It is important to be vigilant about preventing the spread of Parrot's Feather and to properly dispose of any plant material to prevent its introduction into natural waterways.
Parrot's Feather is a versatile and valuable aquatic plant that has many potential benefits. Whether used in aquariums, water gardens, or for medicinal purposes, the plant provides a unique and aesthetically pleasing addition to any aquatic environment.
