Heteranthera zosterifolia

Heteranthera zosterifolia, also known as "Stargrass," is native to South America, particularly regions such as Brazil, Argentina, and Uruguay. It grows in wetlands, ponds, and slow-moving streams, thriving in tropical and subtropical climates. 

Stargrass is highly valued in aquascaping due to its vibrant green color and delicate, feathery leaves. It creates a beautiful contrast when placed in the background or midground of an aquarium or pond. The plant can reach heights of 10-20 inches (25-50 cm), providing a visually striking appearance.

This plant prefers a nutrient-rich substrate and moderate to high lighting conditions. Carbon dioxide (CO2) supplementation may also be beneficial for its growth and vitality. Stargrass can grow relatively fast under suitable conditions, so regular maintenance is essential. Prune any excessive growth to prevent shading of other plants and to maintain the desired appearance. Frequent water changes and proper nutrient dosing are recommended to ensure the plant's health.
