Question
Hello, Here I have an unknown aquatic plant. It grows in a wetland swamp, that dries out when there is little rain that is located in Salem Sound, Massachusetts. I have not noted it to flower. I am hoping it is able to be identified! Thank you very much! SueL-B
Answer
Dear SueLB, you appear to have photographed a large specimen of Ludwigia palustris (common water-primrose). This species has opposite leaves with leaf blades shaped as you have pictured here. It is sometimes a small plant trailing over wet substrate, but in deeper water can be as you have found it. Best wishes.
