Fat duckweed
Lemna gibba
Fat duckweed is a fast-spreading floating aquatic plant that naturally covers the surface of ponds, slow streams, and water features. It thrives in full sun to partial shade and requires no soil — simply place it on calm, nutrient-rich water. Monitor regularly as it can multiply quickly and may need thinning to prevent it from blocking light for submerged plants.
