Equisetum hyemale

Horsetail
Equisetaceae
Ornamental grasses and grasslike plants, Perennials, Aquatic

Rushlike survivor of the Carboniferous Age in Europe and North America. This is the most common species. Slender, hollow, 4-ft. stems are bright green, with a ring of black and ash gray at each joint. Spores are borne in conelike spikes at stem ends. The common name “horsetail” refers to the bushy look produced by the many whorls of slender, jointed green stems that radiate out from joints of main stems on some of the other species.
