About Hieracium laevigatum Willd.
Hieracium laevigatum, commonly called smooth hawkweed, is a Eurasian plant species. It belongs to the tribe Cichorieae, part of the Asteraceae family. It is widespread across most of Europe and western Asia. This species is very similar to Hieracium sabaudum. It grows on dry, more or less nutrient-rich soil, in habitats including open light woods, grassy embankments, fields, and walls.
Smooth hawkweed is an herb that grows up to 60 cm (2 feet) tall. Unlike many related species, its leaves grow along the stem rather than forming a rosette at the base. Its leaves are lance-shaped, reaching up to 10 cm (4 inches) long, and have large teeth along their edges. A single stem branches near the top to produce numerous flower heads. Each flower head holds several ray flowers and contains no disc flowers.
