Giant Duck Weed "Spirodela Polyrhiza"

Giant Duckweed (Spirodela polyrhiza) is a fast-growing floating plant with larger, round leaves compared to common duckweed. Its bright green fronds create a dense mat on the water’s surface, providing natural shade and reducing algae growth by limiting light penetration. Easy to grow, it thrives in still or slow-moving water and quickly absorbs excess nutrients, improving water quality. Perfect for ponds and aquariums, it’s fish- and shrimp-safe, though it may need regular thinning to prevent overcrowding.
