At least, I think this is a yellow flag iris -- that's the best identification I can do through Google. There's thousands of them off Old Creek Road, as well as other parts of the county. It's a non-native species and considered an invasive weed (it's certainly invaded Old Creek and Hunn roads), from what I found online. I got a little obsessed with getting a picture of this one particular plant around noon today -- trying different lenses, exposures, shutter speeds. This was the best I could do.
