Amazon sword plant

The Amazon sword plant (Echinodorus amazonicus) is a prominent aquatic species belonging to the Alismataceae family. It is widely recognized in the aquarium industry as a cornerstone plant due to its hardiness and classic aesthetic, which mimics the natural vegetation of tropical riverbeds.

This species originates from the tropical regions of South America, specifically the Amazon River basin. In its native habitat, it thrives in slow-moving waters and marshy environments, adapting seamlessly to the fluctuating water levels typical of the region. This evolutionary background makes it an excellent choice for beginner and expert aquarists alike.

Botanically, it is characterized by a dense rosette of long, lanceolate leaves that can reach significant heights. The plant features a robust root system that is essential for nutrient uptake from the substrate. Its growth habit is typically upright, making it a perfect choice for the midground or background placement in large-scale aquascaping layouts.

Regarding agrotechnical requirements, the Amazon sword prefers a nutrient-rich substrate and moderate to high lighting conditions. To ensure optimal growth, it is recommended to provide supplemental root fertilizers, as the plant primarily derives nutrients through its roots rather than the water column. Maintaining a consistent temperature between 22°C and 28°C ensures stability and healthy leaf production.

The primary use of this plant is in the ornamental aquarium trade, where it serves as a staple for creating lush, green backgrounds. Common issues include iron deficiency, which manifests as yellowing leaves (chlorosis), and the growth of algae on leaves under excessive light intensity.

• Regular pruning of decaying leaves is recommended.
• Adequate substrate depth is mandatory for root development.
• Iron-rich fertilization is essential for color maintenance.
