About Scouringrush Horsetail (Equisetum hyemale) Equisetum hyemale (Rough Horsetail or Scouring Rush) is a widespread species ative to moist forests, forest edges and stream banks, swamps, fens throughout most of California. It is primarily found in wetlands, and in riparian zones of rivers and streams where it can withstand seasonal flooding. It is also found around springs and seeps, and can indicate their presence when not flowing. Other habitats include moist forest and woodland openings, lake and pond shores, ditches, and marshes and swamps. It has jointed reed-like stalks impregnated with silica which makes them feel rough to the touch. The rough bristles have been used to scour or clean pots, used as sandpaper, as well as to shape the reeds of reed instruments such as clarinets or saxophones. Boiled and dried Equisetum hyemale is used as traditional polishing material like fine grit sandpaper in Japan. Best used in a container. If planted in the ground it can be an aggressive spreader. It is popular on the margin of ponds and bioswales.
