Picris hieracioides, commonly known as hawkweed oxtongue, is a biennial to perennial wildflower native to Europe and western Asia. It is characterized by its rough, bristly leaves and clusters of yellow, dandelion-like flower heads that bloom from midsummer to autumn. The genus name Picris comes from the Greek word for “bitter,” referring to the plant’s sharp-tasting sap. Its colloquial name “oxtongue” alludes to the coarse texture of its leaves, resembling a cow’s or ox’s tongue. Unlike many similar composites, Picris hieracioides thrives in dry, nutrient-poor soils, making it a hardy species of grasslands and roadside habitats.
