Despite being a North American native, Equisetum hyemale brings a unique vertical quality to the landscape with its starkly upright, cylindrical aerial parts. Dating back to prehistoric eras as one of the first vascular plant species according to the fossil record, Equisetum hyemale, known commonly as scouring rush and horsetail, rides the line between fern-relative and perennial-relative. Small, fertile, terminal cones produce spores typically in mid-summer, encouraging a healthy reproduction of the species not only by environmental factors but by prolific rhizomatous growth as well. Although it may become somewhat aggressive in wet, poorly drained areas, horsetail remains evergreen throughout the winter and adds an interesting textural component to the rain, wetland, or a low-lying spot in the medicinal garden.

Traditional use of horsetail as a medicinal herb is said to promote bone, skin, nail, and hair health, as well as being a vulnerary (wound-healer), diuretic, and having many other potential benefits. Although there is limited clinical evidence to support these claims, horsetail has been used in traditional medicine practices since the Ancient Greeks and Romans.
