Lemna trisulca L.

Star duckweed

Lemnaceae (Duckweed Family)

USDA Symbol: LETR

USDA Native Status: Native to U.S.

Duckweeds are useful as a water crop as they can acclimatize themselves to almost all growing conditions, with some thriving in manure-rich or eutrophic waters. They reproduce quickly, extending over large surface areas, and are easily harvested. Their high fat and protein content makes them a source of food for animals and poultry.
Duckweeds have potential in wastewater treatment, absorbing excess nutrients from surface waters, including phosphorus and ammonias, reducing suspended solids, and reducing biochemical oxygen demand.
Eaten by Blue Herons and Moose. (Rook)
