Scrophularia auriculata

Scrophularia auriculata, the shoreline figwort[1] or water figwort, is a perennial plant of the genus Scrophularia in the family Scrophulariaceae. It is found commonly in Western Europe and North Africa, on the margins of rivers, ponds and similar damp places.[2][3] It is an upright plant reaching 70 cm with blunt oval, crenate leaves in alternate pairs on the greenish–purple square stem, most leaves may have two small lobes at their base. The spikes of flowers are held stiffly on square stems which arise from the main stem in the angle of the leaf stalks. The square stems have a wing running down each corner. These wings are more obvious than on the closely related common figwort (Scrophularia nodosa). The flowers are small, maroon-brownish and globular with two small lips above and below. The five sepals are green with a white margin, broader on the water figwort than the common figwort. The plant flowers from June to September after when the flowers produce small spherical to pear-shaped capsules containing a large number of seeds.[2]
