Scouring Rush Equisetum hyemale grows in the wetland around the pond. It is also called 'horsetail'.
This plant's ancestors have been on earth millions of years.
The tough stems can be used as reeds for musical instruments.
They also have coarse fibers and silica deposits, so mammal herbivore don't eat this plant.
Rather than seeds, the Scouring Rush reproduces by spores made by structures on the top of each fertile stem.
