Vallisneria gigantea, also known as Giant Jungle Val or Jumbo Vallisneria, is a popular aquatic plant species found in freshwater environments throughout Asia, Africa, and Australia. As its name suggests, it can grow quite large, with leaves reaching up to 6 feet in length.
 
Caring for Vallisneria gigantea requires a well-lit aquarium with a temperature range between 68-82°F and a pH level between 6.5-8.5. These plants prefer a nutrient-rich substrate, such as a fine gravel or sand, and can be propagated by runners that grow from the base of mature plants.
 
Vallisneria gigantea is an easy plant to care for and can be a good choice for beginners. They are known for their rapid growth rate, which can help to absorb excess nutrients in the aquarium and prevent algae growth. These plants also provide a natural habitat and hiding place for fish and invertebrates.
 
Feeding Vallisneria gigantea is not necessary as they obtain nutrients through their roots and leaves. However, they may benefit from a liquid fertilizer or root tabs placed near their roots to promote growth and vitality.
 
Regular maintenance, including pruning and removing dead or damaged leaves, is essential for the health and appearance of Vallisneria gigantea. They can also benefit from occasional water changes and the addition of carbon dioxide (CO2) to support their growth and development.
