Hieracium nudicaule
Scouler's Woollyweed is a western North American perennial herb in the daisy family, growing up to about 50 cm tall with yellow flower heads. It is a wild native species rather than a common garden plant, so growing it is mainly about mimicking dry, open native habitat.
Hieracium nudicaule is a North American plant species in the tribe Cichorieae within the family Asteraceae. It grows only in the western United States, primarily in California and Oregon, though with a few populations in Washington and northern Idaho.
Hieracium nudicaule is an herb up to 50 cm (20 in) tall, with leaves on the stem and also in a rosette at the bottom. Leaves are up to 120 mm (4.7 in) long, sometimes with teeth on the edges. One stalk can produce 2-12 flower heads in a flat-topped array. Each head has 20-40 yellow ray flowers but no disc flowers.
