Photos taken at Ledges State Park
If I can located a cache near water, we're in good shape. The kids will play for hours in the water while I search for caches. This plant is found in most places where there is a creek bed. You won't find them in the water, but on the creek banks. I include close-up pictures to show the joints (here they look like white rings), the hollow stem (the tip was already broken off when I found this specimen), and a view of the creek bed -- on the left side of the creek (it's really north), what looks like grass is really clumps of scouring rush. I was not able to get a good photo of the cone you find at the tip. All of the photos were tough to get with the weather.
We've found Smooth and Rough Scouring Rushes in various wild places, always near water. The writer of this article says that it's in her housing subdivision. These plants are named "scouring rush" because they were once used for cleaning pots and pans. If you feel one, you'll understand. We've tested it, and maybe you will too. They do not branch and we always find them grouped in a clump. When the kids were very young, they would blow through the hollow stem and try to whistle through them. "N" declared this is favorite plant when he was in preschool.
