Description
Yellow archangel is a large-leaved perennial plant with underground runners growing to a height of about 40 to 80 cm (16 to 31 in). The paired opposite leaves are stalked, broadly ovate with a cordate base and toothed margin. The underside of the leaves is often purplish. The flowers grow in whorls in a terminal spike. The calyx is five-lobed. The corolla is yellow, 15 to 25 mm (0.6 to 1.0 in) long, the petals fused with a long tube and two lips. The upper lip is hooded and the lower lip has three similar-sized lobes with the central one being triangular and often streaked with orange. There are two short stamens and two long ones. The carpels are fused and the fruit is a four-chambered schizocarp
