Hello everyone, new member here. I am in college and I manage a few farms my grandad owns near the Miss. river in Tennessee. I have been engaged in moist soil management for many years without really knowing it. It's not too hard to open some boards/cut beaver dams, and let nature take its course. I have just now began to read on it and realize different drawdowns and different times of the year depict what grows. Well this year I did a late drawdown and I have about 10 acres of this stuff growing.. it's only about 30-40 days in so it might be too young to tell.. can anyone help me I.D. This plant?
