Summary

Hippuris vulgaris, commonly known as Common Mare’s-tail, is an aquatic perennial herb native to a wide range of habitats including marshes, ditches, and the shallow edges of ponds and lakes, primarily in non-acidic waters across Eurasia and North America, from Greenland to the Tibetan Plateau and Arizona. It typically projects stems 8-12 inches above the water’s surface, with the rest of the plant submerged, and can spread to form dense colonies. This plant is characterized by its simple, linear leaves that whorl around the stem, resembling a horse’s tail, and it lacks conspicuous flowers, relying on wind and water for pollination.

Common Mare’s-tail is valued for its use in water gardens and ponds for its oxygenating properties and as a habitat for aquatic wildlife. It is easy to maintain, requiring minimal care once established in a suitable aquatic environment. However, it can become invasive outside its native range, so it is crucial to check local regulations before planting. In cultivation, it prefers full sun to part shade and can tolerate a range of water conditions, from standing water to periodically wet soil.CC BY-SA 4.0
