Its definitely Phragmites. Very invasive plant that has taken over cattail swamps here in Michigan. The state is eradicating it because it's a major problem here. IMHO, don't plant it...
I have seen this stuff along railroad tracks in Missouri and it quickly takes over everything. Seems to be a pretty nasty invasive but it would make a great screen. Imo I would not plant for fear of it taking over my nwsg.
displacing cat tails is a problem, red winged black birds use it as a nesting material and are hard pressed to build with this new fangled phragmites.........
