Scrophularia duplicatosserata is a perennial plant found on forest floors in hilly districts, with rhizomes that become fat and send out fine roots. Stems are soft, have four ridges, are erect, and range in height from 0.4 to 1m. Leaves are of opposite phyllotaxis, each ovate-oblong, 6-11cm long, with 1-3cm long petioles; the margins are sharply double-serrate. Stem tips produce panicles, from which 7-9mm long, dark purple flowers (corollas) emerge. Bloom time: July-September.
