Phragmites aka Phrag aka European Common Reed

[ShadowHM]

Yes. I noticed some years ago a neighbor had planted a pretty stand of tall feathery reeds along the roadway. Now, they have spread for some miles in both directions. I'm sure they are not the only ones. Wouldn't it be nice if the DNR might be able to compel them to clean up their environmental mess.

While I would (and do) frown upon those who plant invasive species, it is entirely likely that the spread of them along roadways is partially caused by municipal and county machinery used to mow the roadsides. Bits and pieces of the mown plants, including but not limited to the seeds, get stuck in the blades and then fall out further down the road. This has helped the the spread of both phragmites and wild parsnip in Ontario.
