Equisetum hyemale v. affine . . Scouring Rush
. . 24to 36 in. . . Sun to lt. shade
. . Zones 2 to 10 . . Avg. to wet soil Native
Round, segmented, reed-like stems are essentially leafless. Evergreen. Stoloniferous. It prefers, but does not require, wet soil. Commonly used at the edge of ponds or streams.
The Equisetum species are found on every continent except Australia. Equisetums have hardly changed since prehistoric times, when they formed a large part of the vegetation that decomposed to form coal seams. They contain alkaloids and various minerals, including silica. Because of the abrasive property of silica, they were used for scouring pots and pans.
. . . . Often found along old railroad tracks, as the rail workers used them for diswashing. The discarded stems took root and flourished.
