Duckweed. It’s a generic term that covers a wide range of free-floating aquatic plants that appear midsummer to blanket the surface of still waters, forming a rippling green mat across quiet bays and coves. The photo above shows at least two different species – large and small.
I enjoy paddling into swaths of duckweed and watching the kayak trace my path through it. And I enjoy seeing where critters have done the same.
