Horsetail is an ancient, evergreen, fern-related plant native to Florida. Its ancestors date back hundreds of millions of years, long before flowering plants evolved. It is especially interesting for its unusual appearance, traditional uses, and ability to thrive in wet environments. Horsetail makes an excellent architectural accent for water gardens, is useful along freshwater pond edges and rain gardens, provides cover for small wildlife near waterway and is also attractive in containers because of its upright stems.

Horsetail was traditionally used to scrub cooking pots, pans, and wooden utensils. Its silica-rich stems act as a natural abrasive, earning it the name Scouring Rush. It has a history of use in herbal medicine, as horsetail is naturally rich in silica, a mineral associated with healthy connective tissues. Historically, horsetail has been used in herbal preparations to support strong hair, nails, skin, and bones. Modern research suggests potential benefits, particularly for brittle nails, although more studies are needed to confirm these effects. It has also been used as a diuretic, for urinary complaints, and has been used traditionally in preparations associated with wound care.

Typically 2–4 feet, occasionally taller, it is perennial and evergreen, with upright, hollow, bendy, bamboo-like green stems.

Growing conditions: Full sun to partial shade; prefers consistently moist or wet soil.
