Egeria najas is a slender, fast-growing stem plant from South America, producing whorls of very fine, narrow leaves along tall, freely branching stems. Its lighter, more delicate structure makes it a visually distinct alternative to the similar Elodea densa, and its vigorous growth enables it to absorb excess nutrients from the water column efficiently.
It is one of the easiest stem plants to keep, growing under low to medium light without CO2 injection. Its rapid uptake of nutrients helps suppress algae in newly established aquariums or tanks with heavier fish loads, making it a practical as well as decorative choice.
Supplied as two bunches, Egeria najas is best planted in groups at the back of the aquarium where it quickly forms a lush, bright green background. Regular trimming keeps growth compact and encourages dense, bushy regrowth from each cutting.
