Our most common species of Equisetum, growing in a wide range of habitats, including cultivated and weedy fields, open woodlands, pastures, roadsides, railroad ballast, sand dunes, sedge meadows, wet prairies, marshes, riverbanks, gardens, etc. Soft pale to brown fertile shoots appear in early spring. They are unbranched, lack stomates, and bear a terminal cone. Sterile shoots emerge typically in May as fertile shoots shed their spores and die. The branches of sterile shoots have 3 or 4 sides and form regular ascending whorls. The branches rarely have secondary branches.
