Last week in my post:
I asked for your help in identifying a plant whose photograph I found in the archive. I did not receive an answer unfortunately. I tried to find this plant with the help of my friend Google and I found out that it is a submersible plant, an excellent oxygenator found in ponds. It sinks to the bottom of the pond in winter to protect itself from the cold and ice and may turn black but as the water warms in the spring it will float back up and turn green again.This can also be useful for oxygenating aquarium water.
I share this picture with Nature Tuesday Challenge
Have you ever seen this plant in your pond?
