Myriophyllum brasiliense

Myriophyllum brasiliense, commonly known as Parrot's Feather, is a species of aquatic plant in the Haloragaceae family. It is native to South America, but has spread to other parts of the world as an invasive species.

Description

Myriophyllum brasiliense is a perennial plant that grows in a variety of aquatic environments. It has a unique appearance, with feather-like leaves that emerge above the water surface. These leaves are bright green and have a delicate, feathery appearance, which gives the plant its common name, Parrot's Feather.

Distribution and Habitat

Myriophyllum brasiliense is native to the Amazon River basin in South America. However, it has been introduced to other parts of the world, including North America, Europe, and Australia, where it has become an invasive species. It thrives in a variety of aquatic habitats, including ponds, lakes, and slow-moving streams.

Invasive Species

In regions where it has been introduced, Myriophyllum brasiliense can become a problematic invasive species. It grows rapidly and can form dense mats that cover the water surface, blocking light and reducing oxygen levels in the water. This can have a negative impact on native aquatic plants and animals.

Control and Management

Efforts to control the spread of Myriophyllum brasiliense include physical removal, the use of herbicides, and biological control methods. However, these efforts can be challenging due to the plant's rapid growth and ability to regenerate from fragments.

Uses

Despite its status as an invasive species, Myriophyllum brasiliense is sometimes used in aquariums and water gardens for its attractive appearance. However, its use is discouraged in many regions due to the risk of it escaping into local waterways.
