Characteristics:

Hairy hawkweed is currently classified as the hound's tongue hawkweed, Hieracium cynoglossum. It is a tall (to 90 cm), stout, erect wildflower with prominently silver-haired stems and leaves. The leaves are very silver-haired, with the basal leaves about 15 to 25 cm long and 1 to 3 cm wide. The middle and upper stem leaves are reduced in size. The flower heads are few to many, with each head having 15 to 50 ray flowers. Individual heads are about 1 cm across. The rays each are tipped with 5 tiny teeth. Before blooming , the flower heads appear as soft, white masses of buds.

Habitat:

Hairy hawkweed is found in dry open places in the lowlands and into the foothills.

Range:

Hairy hawkweed may be found east of the Cascades from southern British Columbia and Alberta south through central Washington to north-eastern Oregon and east to central Idaho and western Montana. It is common in the Palouse country of eastern Washington.
