Smooth Hawkweed

Hieracium laevigatum, or smooth hawkweed, is a Eurasian plant species in the tribe Cichorieae within the family Asteraceae. It is widespread across much of Europe and western Asia. It is very similar to Hieracium sabaudum and can be found on dry, more or less nutrient rich soil in light woods, grassy embankments and fields, or on walls.

Hieracium laevigatum is an herb up to 60 cm (2 feet) tall, with leaves on the stem rather than in a rosette at the bottom. Leaves are lance-shaped, up to 10 cm (4 inches) long, with large teeth along the edge. One stalk branches toward the top, producing numerous flower heads. Each head has several ray flowers but no disc flowers.
