Summary

Equisetum hyemale, commonly known as Scouringrush Horsetail, is an evergreen perennial herb native to a wide range of habitats including wet woodlands, riverbanks, and ditches across Eurasia and North America. It typically grows to a height of 2-4 feet (0.6-1.2 meters) with a spread of 1-1.5 feet (0.3-0.5 meters). The plant features rough, hollow, jointed stems that are medium to dark green and can resemble bamboo. The stems are not true leaves but are photosynthetic and contain silica, which historically made them useful for scouring pots.

Scouringrush Horsetail is valued for its architectural form and texture in the garden, providing year-round interest with its evergreen stems. It is often used in modern and Asian-inspired garden designs, fitting well into narrow spaces and providing a strong vertical accent. It thrives in moist, well-drained soil and can tolerate a range of light conditions from full sun to partial shade. While it requires minimal maintenance, it can spread aggressively by rhizomes and should be planted in contained areas or pots to prevent unwanted spread. It is also important to check its invasive status before planting it outside its native range. It has been found to become invasive in South Africa and Australia, especially in moist habitats.CC BY-SA 4.0
