Characteristics:
Foothill daisy is an attactive perennial wildflower with a cluster of basal
leaves and erect stems rising from 10-50 cm high. The stems are slender, usually
purplish near the base, and often branched above. The herbage is usually densely
covered with spreading hairs less than 1 mm in length. The leaves are linear
to narrowly oblanceolate and distinctly 3-nerved. The basal leaves range from
5-20 cm long and taper to a slender petiole. The several stem leaves are much
reduced in size.
The inflorescence includes one to sixteen flower daisy-like flower heads,
each on long peduncles. The involucre is closely short-villous, 5-7 mm high,
and has narrow, awl-shaped bracts. The 30-65 violet to white rays surround a
yellowish central disk. Individual rays are 7-13 mm long.
Habitat:
Foothill daisy may be found in dry open woods and in the sagebrush plains.
Range:
Foothill daisy may be found from southern British Columbia south to the east
of the Cascade Mts. to eastern Oregon and east to Montana and Wyoming.
