Field Horsetail
Equisetum arvense L.
An upright perennial spreading by deep, dark underground rhizomes and with two distinct above ground shoots . The first to emerge is a grey-brown unbranched, hollow, jointed shoot with toothed sheaths and with a terminal spore-producing ‘cone’. Next emerges a pine tree-like green leafless, hollow, jointed shoot with whorls of green, jointed branches.
