tall annual grass for screen in zone 5

I need to do some spot screening of the road and neighbors in 4 spots in my very traditional style and smallish yard. I've not used grasses anywhere. I want to be careful about incorporating them into my old fashioned style garden. I don't want them to stick out like a sore thumb. (I have lilacs, peonies, delphinium, iris.) My house is a large victorian, but the yard is small
I say annual to avoid the spread/dividing issue. (I just wrestled two huge siberian irises out of the garden yesterday!!)
I'd like something 5-8' tall. I did see the great Chicago photo of the P. Prince, but how long would it take to reach this size? I can link to some photos of the yard if that would help.

TIA for any ideas

5-8' from an annual ornamental grass in your zone won't be easy to accomplish. You might do better with a well-contained perennial grass, like Panicum virgatum or Miscanthus. If you constrain these grasses with root barriers, you can control their spread for some years, although eventually, division will be required.

There are annual meadow grasses which can reach these heights in a season, but many of them can self-seed rather easily.

Thanks for replying, Donn

I understand the root barrier method, but my "soil" isn't deep enough for that, I don't believe. I guess I'll have to consider something else.
