Figwort (Scrophularia nodosa)
Widespread herbaceous perennial in the Northern hemisphere growing to 1 m (3ft). Prefers a damp, even marshy habitat, in sun or part shade. Flowers from June to September, with the seeds ripening from July to September. Awesome pollinator attractor. Medicinally used for skin problems, sprains, swellings, burns, inflammation, and even gangrene. Also considered as a cleansing herb that supports the detoxification of the body. Sow spring or autumn, ideally in a cold frame. Also called Woodland Figwort, Common Figwort, or Knotted Figwort.
(The name Scrophularia comes from scrofula, a form of tuberculosis of the lymphatic glands that figwort was historically used to treat.)
