Myriophyllum mattogrossense

Myriophyllum mattogrossense, commonly known as the Red Water Milfoil, is a perennial aquatic plant species belonging to the Haloragaceae family. Recognized for its feathery, delicate leaf structure and rapid growth rate, it is a highly valued specimen in both professional aquascaping and experimental aquatic cultivation.

The species originates from the Mato Grosso region in Brazil, South America. Its natural habitat includes slow-moving, warm tropical rivers and marshes. Due to its popularity in the aquarium trade, it has been successfully introduced to various environments globally, provided the climate conditions mimic its native tropical, nutrient-rich waterways.

Botanically, the plant features long, robust stems that produce whorls of fine, pinnate leaves. Depending on environmental conditions, such as light intensity and nutrient availability, the leaves can shift from bright green to vibrant orange-red shades. The plant relies primarily on nutrient uptake through its foliage, making it a very effective natural water purifier.

Cultivation requirements involve high-intensity lighting, a steady supply of CO2, and a substrate enriched with micronutrients, particularly iron. The optimal temperature range is between 22°C and 28°C. Proper pruning is an essential agrotechnical practice: regular trimming encourages denser branching and prevents the base of the plant from shedding leaves due to light starvation.

In terms of хозяйственное использование, this plant is used extensively in botanical research and aquarium decor to manage nitrogen cycles in closed aquatic systems. Common challenges include algae infestation on the feathery leaves, which can be mitigated by ensuring proper water circulation and managing nutrient input. Pests such as snails are typical adversaries, requiring careful monitoring.
