Horsetails at Roadmire

The Horsetails at Roadmire are beautiful. Their stalks and leaves are covered in harsh mineral silica. They’re a bit scratchy and hard on your hands. They were used to scour metal pans, particularly those made of tin.

They haven’t changed much in millions of years. They don’t have flowers and they don’t have seeds. They reproduce using spores, in a similar way to ferns. They’ve been on Earth for 150 million years.

They’ll still be here long after we’ve gone.
