Swamps and moist forests; coniferous, mixed or deciduous, moist thickets; often on forest edges or even in open meadows and swales northward; rare southward.
This is a distinctive species with the coppery sheaths on the main stem, and beautiful with the primary branches consistently again gracefully branched, unlike all our other species. The stems typically arch, with the whorls of branches giving a distinctive layered look. Equisetum sylvaticum colonies are regularly fertile and also reliably produce symmetrical branches on fertile shoots as the strobili mature, making recognition easy.
