In the public lake near my house, I think there might be some kind of Utrics in the swampy area. It looks like a picture I saw. So does a bunch of these plants that I keep finding on my hook when I go fishing. What I was wondering is, would it be ok to pick a peice of it and grow it? I read that they're invasive or something, and this one thread said it would probably be ok to pick some, but I don't want to pick anything that's endangered. It's a public lake so I don't know who to ask permission from, if there is anyone. Plus I don't know what kind of Utric it is, if it is one.
