Characteristics:
Gray hawksbeard is a one or two-stemmed perennial from a taproot,
arising from 20-70 cm in height. Its herbage is varied, often being densely
gray-haired (like thin felt) to sparsely gray haired. The basal and stem leaves
vary from 10-40 cm long, and are pinnatifid with many entire to toothed lobes.
The inflorescence contains from 10-60 flower heads, with each
head having 7-12 ray flowers. The involucre is 10-16 mm tall, sometimes smooth
but more commonly gray haired. The outer bracts (barely seen at the base of
the involucre in the photo above) are very short in contrast to the long inner
bracts (which normally number from 7-8).
Habitat:
Gray hawksbeard is a plant of dry, open places in the foothills
and plains.
Range:
Gray Hawksbeard is found east of the Cascade Mts. from central
Washington south to California and eastward to Colorado, Wyoming and then north
to Alberta.
