If it was blooming, I'd know for sure, but my guess is water forget-me-not Myosotis scorpiodes. I had never heard of this plant until I got some in a trade, and the person who gave them to me said she found them growing wild in a pond or stream nearby.
Hello All and thanks for all the great suggestions as to the identity of this plant. I'm going to take another look at it today and see if it has changed in appearance. It does look like Water Hawthorne, but I would be surprised to find any growing wild here. More likely that it is the Pond Weed... If it has changed dramatically, I'll post another picture.
Well I took another look and I'd say it's changed a bit.
I'm posting a picture of how it looks today. (In this forum) I'll title it Still trying to identify this water plant. Please take a look and tell me what you think.
In the description of Pond Weed it doesn't mention or show leaves as this one is displaying now.
If there is a way to add two pictures to one post, let me know, but adding another post is the only way I know to do this.
If you look at the second posting of this plant you will see that we have decided it is Pickerel Weed. I never knew that it started out with floating leaves, nor was I aware that it could be found in the wild in zone 5. (hardy zones 4-11)
Thanks for all the help,
