"Equidistance" is a dwarf horsetail originally found in Central Michigan on a sand flat growing in a compacted soil few other plants could tolerate. There it created a dense sod with a matrix of small rhizomes. Each plant produces a straight stalk to 8 inches high with no side branching. Very easy selection to grow in a wide variety of soils including wet and soggy soil.
Horsetail's silica-based stems are great for polishing and washing metal, hence the name ‘pot scrubbing plant’. The plants have been trialed for phyto-remediation. They are able to a absorb gold up to 4.5 ounces/ton of fresh stalks. Native Americans used the tiny tubers as a source of food and allowed horses to graze on it. Can grow in sun or light shade.
