Rough horsetail

Equisetum hyemale, commonly known as rough horsetail or scouring rush, is an evergreen perennial herbaceous pteridophyte in the horsetail family Equisetaceae native to Eurasia and Greenland. It was formerly widely treated in a broader sense including a subspecies (subsp. affine) in North America, but this is now treated as a separate species, Equisetum praealtum.
