Creeping perennial of woodland and hedgerows, this handsome plant bears its bright yellow flowers in whorls on erect stems from April to June. The two-lipped flowers (20-25mm) are extremely attractive when viewed closely, with their upper lip somewhat hooded and fringed with hairs, and their lower lip streaked red-brown. The dark green leaves are narrow, lanceolate and stalked.
