The photo at right shows a close-up of the flower head of shaggy fleabane
as seen in sandy soils along Crab Creek in central Washington.........June 22, 2006. 50-100 narrow ray flowers radiate from the central disk. These may range from white to pink or pale blue in color.
Characteristics:
Shaggy Fleabane, as its name indicates, is a copiously haired perennial with
several leafy stems that ranges in height from 5 - 50 cm tall. The stems and
leaves are covered with numerous spreading-hairy, and sometimes somewhat glandular
hairs. The leaves are linear-oblanceolate to oblanceolate, olive-green in color,
up to 8 cm in length and 8 mm in width. The leaves may be found along the entire
stem as well as at the base, but are reduced in size from about mid-stem.
The daisy-like flower heads have numerous (50- 100) white, pink, or light
blue rays surrounding a narrow (7- 15 mm wide) disk of yellow disk flowers.
The narrow ray flowers are usually about 0.7- 1.5 mm wide and 6- 15 mm long
while the disk flowers are about 3.5- 5 mm long. The involucre is about 4- 7
mm tall, finely hairy and glandular, with bracts in one row.
Habitat:
Shaggy Fleabane is found in dry open places, often with sagebrush. It is found
primarily in the valleys and foothills at lower elevations to the higher elevation
foothills and sagebrush desert.
Range:
Erigeron pumilus is found from southern British Columbia, southwards
east of the Cascade Mountains through Washington and Oregon, to the coast of
southern California. It is found eastward to Saskatchewan, the western Great
Plains, and northern New Mexico and Arizona.
